LUXBIN Quantum Echo Loop

Multi-backend quantum message relay using triple-encoded qubit states on IBM quantum hardware.

🛰️ NEW: LUXBIN Quantum Grid — Quantum-secured smart grid infrastructure designed for Starlink mesh networks. See the full ecosystem below.

Three IBM quantum computers (ibm_fez, ibm_torino, ibm_marrakesh) communicate by passing encoded messages through a continuous loop. Each character is encoded across the full Bloch sphere using three physical channels mapped to the three rotation axes:

Channel	Physical Basis	Qubit Gate	Range
Light	Wavelength (400–700 nm)	RY	Visible spectrum
Sound	Frequency (262–2349 Hz)	RZ	Musical notes A–Z
Microwave	Frequency (4–8 GHz)	RX	Transmon qubit range

This gives full Bloch sphere coverage — every character occupies a unique point in 3D qubit state space.

How It Works

Each loop iteration sends a 5-character message through a pipeline across all three IBM quantum backends:

NICHE → [Echo] → [Relay Leg 1] → [Relay Leg 2] → [Relay Leg 3]
    ↑       ibm_fez    ibm_fez      ibm_torino     ibm_marrakesh
    |                                                     |
    |   [Final Echo] ← [Ping-Pong] ← [Consensus Vote] ←─┘
    |      ibm_fez    fez↔torino    fez+torino+marrakesh
    └──────────────────────┘
         output → next input

Pipeline Stages

1. Echo — Encode message with H + triple-rotation + entanglement chain + QFT-like transform. Baseline quantum fingerprint.
2. Relay Race — Three legs across three backends. Each leg applies different gate sequences (phase shifts, swaps, cyclic entanglement) simulating signal propagation through different media.
3. Consensus Vote — All three backends independently process the same state. Majority vote across backends determines each character.
4. Ping-Pong — Two backends bounce the message with forward/reverse encoding (conjugate operations), testing round-trip fidelity.
5. Final Echo — Output becomes the next loop's input. The loop runs indefinitely.

Triple Decoding

Each measurement result is decoded through all three channels independently. The final character is chosen by majority vote — if 2 of 3 channels agree, that character wins. This provides error resilience against single-channel noise.

votes = [wavelength_to_char(wl), frequency_to_char(freq), microwave_to_char(mw)]
winner = Counter(votes).most_common(1)[0][0]

Results

The loop has been tested on real IBM hardware. Each iteration submits ~10 jobs across three backends:

Loop	Input	Output	Jobs	Time
1	NICHE	FPZ	10	66.7s
2	FPZ	P XU	10	118.6s

Job IDs are logged for verification on the IBM Quantum dashboard.

Quick Start

Prerequisites

pip install qiskit qiskit-ibm-runtime numpy

Run (Local Simulator)

python luxbin_quantum_full_experiment.py

Run (Real IBM Hardware)

export IBM_QUANTUM_TOKEN="your-token-here"
python luxbin_persistent_loop.py

The loop runs in the foreground with graceful shutdown on Ctrl+C. To run in the background:

nohup python3 -u luxbin_persistent_loop.py > loop_output.log 2>&1 &

Run (Single Shot)

export IBM_QUANTUM_TOKEN="your-token-here"
python luxbin_ibm_live.py

Encoding Reference

Each character A–Z (plus space) maps to specific values across all three channels:

Character  Light (nm)  Sound (Hz)  Microwave (GHz)
    A        400.0       440.0         4.000
    N        450.6      1174.7         6.000
    I        431.2       880.0         5.231
    C        407.8       523.3         4.308
    H        427.3       830.6         5.077
    E        415.6       659.3         4.615

The microwave range (4–8 GHz) was chosen to match the operating frequency of IBM's transmon superconducting qubits.
