Future iterations might include +other types, especially to bolster error modeling. Here's a quick breakdown of the `"type"`s: + +- `"data"`: Directives specifically related to data handling such as the creation of variables. +- `"cop"`: Refers to classical operations. This includes actions like defining/assigning classical variables or +executing Boolean/arithmetic expressions. +- `"qop"`: Denotes quantum operations. These encompass actions like executing unitaries, measurements, and initializing +states. +- `"mop"`: A machine operation, which represents changes in the machine state. For example, idling, transport, etc. +- `"block"`: Facilitates grouping and control flow of the encapsulated blocks/operations. + +A comprehensive explanation of these operations and blocks is given in the following sections. + +## Data Management + +These operations deal with data/variable handling such as data definition and exporting, helping to structure the +information flow in the program. In the future, the `"data"` type may be utilized to create and manipulate data +types/structures such as arrays, data de-allocation, scoping, etc. + +### Defining Classical Variables + +In the current implementation, classical variables are defined as globally accessible, meaning they exist in the +top-level scope. The lifespan of a classical variable extends until the program concludes. Once a classical variable and +its associated symbol are created, they remain accessible through the entirety of the program. The symbol consistently +refers to the same memory location. By default, classical variables are represented as i64s. The value of these +variables can be modified through assignment operations. + +To define or create a variable, the following structure is employed: + +```json5 +{ + "data": "cvar_define", + "data_type": str, // Preferably "i64" + "variable": str, // The variable symbol + "size": int // Optional +} +``` + +- `"data_type"`: One of "i64", "i32", "u64", "u32". +- `"variable"`: Represents the symbol tied to the classical variable. By default, all variables are initialized with a +value of 0. +- `"size"`: Even though every variable is internally represented as an i64, a size can be specified. This correlates +with the size in OpenQASM 2.0's `creg sym[size];`. If omitted, `"size"` defaults to the bitsize of the integer +representation (e.g., 32 for i32, 64 for i64, etc.). During classical computations, all variables behave as complete +i64s. However, when assigned, the bits are restricted to the number defined by `"size"`. For instance, in OpenQASM 2.0, +executing `creg a[2]; a = 5;` results in `a` holding the value 3 (`0b111` becomes `0b011` since `a` is restricted to 2 +bits). + +To prevent runtime errors, ensure a classical variable is defined prior to its usage. Given their global scope and the +necessity for prior definition, it's advisable to declare variables at the program's onset. + +### Exporting Classical Variables + +At the conclusion of a simulation or quantum computation, you might want to extract or "export" certain classical +variables. This mechanism allows users to retrieve selected results from their computations. This mechanism also allows +a program to have an internal representation of variables and/or scratch space/helper variables and to then present the +user with only the information they requested. In PHIR, the structure to accomplish this is: + +```json5 +{ + "data": "cvar_export", + "variables": [str, ...], // List of classical variable symbols to export. + "to": [str, ...], // Optional; rename a variable upon export. +} +``` + +It's worth noting that if no specific export requests are made, PECOS will default to exporting all classical variables. +These will be made available in the user's final results dictionary post-simulation. + +### Defining Quantum Variables + +To define a set of qubits and associate them with quantum variables: + +```json5 +{ + "data": "qvar_define", + "data_type": "qubits", // Optional + "variable": str, // Symbol representing the quantum variable. + "size": 10 // Number of qubits +} +``` + +Much like classical variables, quantum variables exist in the top-level scope. These are accessible throughout the +program and defined for its entirety. An individual qubit is denoted by the qubit ID `[variable_str, qubit_index]`. For +instance, the 1st qubit of the quantum variable `"q"` is represented as `["q", 1]`. + +## Classical operations + +Classical operations are all those operations that manipulate classical information. In the current PECOS +implementation, all classical variables are implemented as 64-bit signed integers (i64). + +### Assigning values to Classical Variables + +Assigning a value to a classical variable involves updating the underlying i64 to a new integer value. The structure for +this assignment in PHIR is: + +```json5 +{ + "cop": "=", + "args": [int | int_expression], + "returns": [str] // variable symbol +} +``` + +Currently, only one variable can be assigned at a time; however, the `"args"` and `"returns"` syntax with a corresponding +list of variables is used to be consistent with the measurement and foreign function syntax discussed below, as well as +to leave open the possibility of supporting destructuring of tuples/arrays in the future. + +In PHIR, specific bits of an integer can be addressed in an array-like syntax, mirroring the `a[0]` notation in OpenQASM +2.0. To reference a bit of a variable in PHIR, use the structure `["variable_symbol", bit_index]`. The assignment +structure then appears as: + +```json5 +{ + "cop": "=", + "args": [int | int_expression], + "returns": [ [str, int] ] // bit_id -> [str, int] +} +``` + +Regardless of assigned `"value"`, when updating a single bit, only the least significant bit (0th bit) of the value is +taken into consideration. + +The term `int_expression` has been introduced and will be elaborated upon in the upcoming sections. Essentially, +`int_expression` encompasses classical operations that ultimately yield an integer value. + +### Integer Expressions + +In PHIR, an integer expression encompasses any combination of arithmetic, comparison, or bitwise operations, including +classical variables or integer literals, that results in an integer value. While future iterations of PHIR and PECOS may +introduce other expression types (e.g., floating-point expressions), the current version strictly supports integer +expressions. The table provided below (Table I) details the list of supported classical operations (`cops`) that can be +used within these expressions as well as assignment operations. + +Constructing these expressions follow an Abstract Syntax Tree (AST) style, utilizing the below formats: + +#### General Operations + +```json5 +{ + "cop": "op_name", + "args": [cvariable | [cvariable, bit_index] | int | {int_expression...}, ...] +} +``` + +#### Unary Operations + +```json5 +{ + "cop": "op_name", + "args": [cvariable | [cvariable, bit_index] | int | {int_expression...}] +} +``` + +#### Binary Operations + +```json5 +{ + "cop": "op_name", + "args": [ + cvariable | [cvariable, bit_index] | int | {int_expression...}, + cvariable | [cvariable, bit_index] | int | {int_expression...} + ] +} +``` + +**Important NOTE:** While PECOS is designed to handle comparison operations within expressions, extended OpenQASM is +not. Consequently, when translating from extended OpenQASM 2.0 to PHIR, restrict expressions to only arithmetic and +bitwise operations. For instance, `a = b ^ c;` is valid, whereas `a = b < c` is not. In OpenQASM 2.0's `if()` +statements, a direct comparison between a classical variable or bit and an integer is the only permitted configuration. +In PECOS implements true comparisons to evaluate to 1 and false ones to evaluate to 0. + +#### Table I - Cop Assignment, arithmetic, comparison, & bitwise operations + +| name | # args | sub-type | description | +| ------ | ------ | ---------- | ---------------------- | +| `"="` | 2 | Assignment | Assign | +| `"+"` | 2 | Arithmetic | Addition | +| `"-"` | 1 / 2 | Arithmetic | Negation / Subtraction | +| `"*"` | 2 | Arithmetic | Multiplication | +| `"/"` | 2 | Arithmetic | Division | +| `"%"` | 2 | Arithmetic | Modulus | +| `"=="` | 2 | Comparison | Equal | +| `"!="` | 2 | Comparison | Not equal | +| `">"` | 2 | Comparison | Greater than | +| `"<"` | 2 | Comparison | Less than | +| `">="` | 2 | Comparison | Greater than or equal | +| `"<="` | 2 | Comparison | Less than or equal | +| `"&"` | 2 | Bitwise | AND | +| `"\|"` | 2 | Bitwise | OR | +| `"^"` | 2 | Bitwise | XOR | +| `"~"` | 1 | Bitwise | NOT | +| `"<<"` | 2 | Bitwise | Left shift | +| `">>"` | 2 | Bitwise | Right shift | + +#### Integer Expression and Assignment Example + +For illustrative purposes, let's explore how `b = (c[2] ^ d) | (e - 2 + (f == g));` would be represented in PHIR: + +```json5 +{ + "cop": "=", + "args": [ + {"cop": "|", + "args": [ + {"cop": "^", "args": [["c", 2], "d"]}, + {"cop": "+", "args": [ + {"cop": "-", "args": ["e", 2]}, + {"cop": "==", "args": ["f", "g"]} + ]} + ] + } + ], + "returns": ["b"] +} +``` + +This example elucidates how intricate expressions are structured in a hierarchical, tree-like manner within PHIR. + +### Exporting Results with the Result Command + +The Result command enables mapping internal measurement results to exported variables in the final output. This operation is essential for specifying which measurement results should be exposed to the user and under what names. + +```json5 +{ + "cop": "Result", + "args": [...], // Source registers or bits to export + "returns": [...] // Names under which to export the results +} +``` + +The Result command supports several formats for both args and returns: + +- Single bit export: `["m", 0]` for a specific bit +- Entire register export: `"m"` for the whole register +- Multiple variable export: using multiple entries in the arrays + +When executed, this operation takes the current values from the source registers and makes them available in the final results under the specified export names. The Result command acts as an explicit declaration of program outputs, allowing internal implementation details and temporary values to remain hidden. + +#### Examples + +**Export a specific bit:** +```json5 +// Export measurement result from bit 0 of register "m" as bit 0 of "q0_result" +{"cop": "Result", "args": [["m", 0]], "returns": [["q0_result", 0]]} +``` + +**Export entire registers:** +```json5 +// Export entire "m" register as "results" +{"cop": "Result", "args": ["m"], "returns": ["results"]} +``` + +**Export multiple registers or bits:** +```json5 +// Export multiple registers at once +{"cop": "Result", "args": ["m1", "m2"], "returns": ["results1", "results2"]} + +// Export multiple bits with different mappings +{"cop": "Result", + "args": [["m", 0], ["m", 1]], + "returns": [["results", 0], ["results", 1]]} +``` + +The ability to export multiple values in a single Result command aligns with the general semantics of other commands in the PHIR specification, providing a consistent interface. + +*Note:* Added in specification v0.1.1 + +### Calling External Classical Functions + +In PECOS, it's possible to invoke external classical functions, especially using entities like WebAssembly (Wasm) +modules. This functionality broadens the expressive power of PECOS by tapping into the capabilities beyond quantum +operations. The structure for representing such "foreign function calls" in PHIR is: + +PECOS can make foreign function calls utilizing objects such as Wasm modules. The structure is: + +```json5 +{ + "cop": "ffcall", + "function": str, // Name of the function to invoke + "args": [...], // List of input classical variables or bits + "returns": [...], // Optional; List of classical variables or bits to store the return values. + "metadata": { // Optional + "ff_object": str, // Optional; hints at specific objects or modules providing the external function. + ... + } +} +``` + +When interacting with external classical functions in PHIR/PECOS, it's crucial to recognize that these external object +can maintain state. This means their behavior might depend on prior interactions, or they might retain information +between different calls. Here are some important considerations about such stateful interactions. + +- *Stateful Operations in extended OpenQASM 2.0:* Extended OpenQASM 2.0 and its implementation recognizes the potential +statefulness of these objects. Therefore, foreign function calls in this environment are designed to be flexible. They +don't always mandate a return value. For instance, a QASM program can interact with the state of an external classical +object, possibly changing that state, without necessarily fetching any resultant data. +- *Asynchronous Processing:* These classical objects can process function calls asynchronously, operating alongside the +primary quantum or classical computation. This allows for efficient, non-blocking interactions. +- *Synchronization Points:* If a return value is eventually requested from a stateful object, it acts as a +synchronization point. The primary program will pause, ensuring that all preceding asynchronous calls to the external +object have fully resolved and that any required data is available before processing. + +## Quantum operations + +The generic qop gate structure is: + +```json5 +{ + "qop": str, + "angles": [[float...], "rad" | "pi"], // Include if gate has one or more angles. + "args": [qubit_id, ... | [qubit_id, ... ], ...], // Can be a list of qubit IDs or a list of lists for multi-qubit gates. + "metadata": {}, // Optional metadata for potential auxiliary info or to be utilized by error models. + "returns": [[str, int], ...] // Include if gate produces output, e.g., a measurement. +} +``` + +`"angles"` is a tuple of a list of `float`s and a unit. +The units supported are radians (preferred) and multiples of ᴨ (pi radians). + +Table II details the available qops. + +For qops like `H q[0]; H q[1]; H q[4];` in QASM, it is translated as: + +```json5 +{ + "qop": "H", + "args": [ + ["q", 0], + ["q", 1], + ["q", 4] + ] +} +``` + +However, multi-qubit gates, such as `CX`, use a list of lists of qubit IDs. E.g., +`CX q[0], q[1]; CX q[3], q[6]; CX q[2], q[7];` in QASM, can be represented as: + +```json5 +{ + "qop": "CX", + "args": [ + [["q", 0], ["q", 1]], + [["q", 3], ["q", 6]], + [["q", 2], ["q", 7]] + ] +} +``` + +PECOS ensures all qubit IDs in `"args"` are unique, meaning gates don't overlap on the same qubits. + +For gates with one or multiple angles, angles are denoted as a list of floats and a unit in the `"angles"` field: + +```json5 +{ + "qop": "RZZ", + "angles": [[0.173], "rad"], + "args": [ + [ ["q", 0], ["q", 1] ], + [ ["q", 2], ["q", 3] ] + ], + "metadata": {"duration": 100} +} +``` + +```json5 +{ + "qop": "U1q", + "angles": [[0.524, 1.834], "rad"], + "args": [ + [ ["q", 0], ["q", 1], ["q", 2], ["q", 3] ] + ], + "metadata": {"duration": 40} +} +``` + +For a Z basis measurement on multiple qubits: + +```json5 +{ + "qop": "Measure", + "args": [ ["q", 0], ["q", 1], ["q", 2], ["q", 3] ], + "returns": [ ["m", 0], ["m", 1], ["m", 2], ["m", 3] ] +} +``` + +### Table II - Quantum operations + +| name | alt. names | # angles | # qubits | matrix | description | +| ------------ | ----------------- | -------- | -------- | ------ | ------------------------ | +| `"Init"` | | 0 | 1 | ... | Initialize qubit to \|0> | +| `"Measure"` | | 0 | 1 | ... | Measure qubit in Z basis | +| `"I"` | | 0 | 1 | ... | Identity | +| `"X"` | | 0 | 1 | ... | Pauli X | +| `"Y"` | | 0 | 1 | ... | Pauli Y | +| `"Z"` | | 0 | 1 | ... | Pauli Z | +| `"RX"` | | 1 | 1 | ... | Rotation about X | +| `"RY"` | | 1 | 1 | ... | Rotation about Y | +| `"RZ"` | | 1 | 1 | ... | Rotation about Z | +| `"R1XY"` | `"U1q"` | 2 | 1 | ... | | +| `"SX"` | | 0 | 1 | ... | Sqrt. of X | +| `"SXdg"` | | 0 | 1 | ... | Adjoint of sqrt. of X | +| `"SY"` | | 0 | 1 | ... | Sqrt. of Y | +| `"SYdg"` | | 0 | 1 | ... | Adjoint of sqrt. of Y | +| `"SZ"` | `"S"` | 0 | 1 | ... | Sqrt. of Z | +| `"SZdg"` | `"Sdg"` | 0 | 1 | ... | Adjoint of sqrt. of Z | +| `"H"` | | 0 | 1 | ... | Hadamard, X <-> Z | +| `"F"` | | 0 | 1 | ... | X -> Y -> Z -> X | +| `"Fdg"` | | 0 | 1 | ... | | +| `"T"` | | 0 | 1 | ... | | +| `"Tdg"` | | 0 | 1 | ... | | +| `"CX"` | `"CNOT"` | 0 | 2 | ... | | +| `"CY"` | | 0 | 2 | ... | | +| `"CZ"` | | 0 | 2 | ... | | +| `"RXX"` | | 1 | 2 | ... | Rotation about XX | +| `"RYY"` | | 1 | 2 | ... | Rotation about YY | +| `"RZZ"` | `"ZZPhase"` | 1 | 2 | ... | Rotation about ZZ | +| `"R2XXYYZZ"` | `"RXXYYZZ"` | 3 | 2 | ... | RXX x RYY x RZZ | +| `"SXX"` | | 0 | 2 | ... | Sqrt. of XX | +| `"SXXdg"` | | 0 | 2 | ... | Adjoint of sqrt. of XX | +| `"SYY"` | | 0 | 2 | ... | Sqrt. of YY | +| `"SYYdg"` | | 0 | 2 | ... | Adjoint of sqrt. of YY | +| `"SZZ"` | `"ZZ"`, `"ZZMax"` | 0 | 2 | ... | Sqrt. of ZZ | +| `"SZZdg"` | | 0 | 2 | ... | Adjoint of sqrt. of ZZ | +| `"SWAP"` | | 0 | 2 | ... | Swaps two qubits | + +## Machine operations + +Machine operations (`"mop"`s) are operations that represent changes to the machine state such as the physical passage of +time or the movement of qubits as well as other aspects that are more directly related to a physical device although potentially +indirectly influencing the noise being applied via the error model. + +The general form of `"mop"`s is: + +```json5 +{ + "mop": str, // identifying name + "args": [qubit_id, ... | [qubit_id, ... ], ...], // optional + "duration": [float, "s"|"ms"|"us"|"ns"], // optional + "metadata": {} // Optional metadata for potential auxiliary info or to be utilized by error models. +} +``` + +The `"duration"` field supports seconds (s), milliseconds (ms), microseconds (us), and nanoseconds (ns) as its units. + +Currently, `"mop"`s are more defined by the implementation of the Machine and ErrorModel classes in PECOS. Therefore, +the `"metadata"` tag is heavily depended upon to supply values that these classes expect. An example of indicating +idling and transport include: + +```json5 +{ + "mop": "Idle", + "args": [["q", 0], ["q", 5], ["w", 1] ], + "duration": [0.000123, "s"] // typically in seconds +} +``` + +```json5 +{ + "mop": "Transport", + // potentially using "args" to indicate what qubits are being transported + "duration": [0.5, "ms"] + "metadata": {...} // potentially including what positions to and from qubits moved between or what path taken +} +``` + +The "Skip" `"mop"` is the empty operation that indicates *do nothing*. It is used in place of operations that will +have no effect on the machine state, such as the global phase operation. + +```json5 +{ + "mop": "Skip", +} +``` + +## Blocks + +In the present version of PHIR/PECOS, blocks serve a dual purpose: they group operations and other blocks, and they +signify conditional operations and/or blocks. In the future, blocks may be utilized to represent more advanced control +flow. A notable aspect of blocks, is that they can encompass any other operation or block, offering a capability for +nesting. + +### Basic block + +The foundation block simply sequences operations and other blocks + +```json5 +{ + "block": "sequence", + "ops": [{...}, ...], + "metadata": {...} // Optional +} +``` + +### QParallel block + +A grouping of quantum operations to be performed in parallel. + +```json5 +{ + "block": "qparallel", + "ops": [{...}, ...], + "metadata": {...} // Optional +} +``` + +The following example contains 6 RZ gate applications. There is 1 `"qop"` per unique gate angle, each with 2 qubit arguments. +All gates within the block will be applied in parallel. + +```json5 +{ + "block": "qparallel", + "ops": [{"qop": "RZ", "angles": [[1.5], "pi"], "args": [["q", 0], ["q", 1]]}, + {"qop": "RZ", "angles": [[1.0], "pi"], "args": [["q", 2], ["q", 3]]}, + {"qop": "RZ", "angles": [[0.5], "pi"], "args": [["q", 4], ["q", 5]]} + ] +} +``` + +### If/else block + +An if-else block: + +```json5 +{ + "block": "if", + "condition": {}, + "true_branch": [{...}, ...], + "false_branch": [{...}, ...] // This is optional and should only be include if an 'else' branch exists. +} +``` + +The `"condition"` field houses a classical expression representable in PHIR. However, it's noteworthy that the extended +OpenQASM 2.0 restricts conditions to direct comparisons between classical variables or bits and integer literals. For +instance, when translating from extended OPenQASM 2.0, acceptable conditions would be `if(a > 3) ops` or +`if(a[0]>=1) ops;`. The extended OpenQASM 2.0 language explicitly avoids permitting multiple comparisons or +bitwise/logical operations, or comparisons between two variables and/or bits. In execution, if a comparison evaluates to +0, PECOS will initiate the `"false_branch"`; otherwise, the `"true_branch"` will be triggered. + +*Note:* While PHIR/PECOS can effectively manage nested if/else statements, extended OpenQASM 2.0 strictly permits only +non-nested if statements.
