IBM Quantum Hardware Benchmarks

Real results from real quantum hardware — validated on IBM Quantum Cloud

Supported Hardware

Quantum Nexus connects directly to IBM Quantum Cloud, with ESCORT routing optimizing circuit execution on each backend:

IBM Torino — 133 Qubits

The latest generation Heron processor. Our QSAM circuits achieve consistent 95%+ fidelity with SCORE correction on this backend.

IBM Sherbrooke — 127 Qubits

Eagle processor architecture. Primary backend for cancer drug screening and financial prediction circuits. CHSH Bell Test S-values consistently 2.6-2.82 (classical bound: ≤2).

IBM Brisbane — 127 Qubits

Secondary Eagle processor used for entanglement verification and QEL cross-system bridge experiments.

Local Simulator

32-qubit local simulation for testing and development. All circuits can be validated locally before submission to quantum hardware.

Quantum-AI Performance Metrics

The 13th Chamber Score evaluates quantum-AI system effectiveness:

QSS (Quantum Speedup Score) = T_classical / T_quantum
Measures computational acceleration over classical approaches.

AIS (Accuracy Improvement Score) = (A_quantum – A_classical) / A_classical
Assesses improvement in solution accuracy or quality.

RES (Resource Efficiency Score) = R_classical / R_quantum
Compares resource utilization — memory, energy, qubits.

13th Chamber Composite Score = w₁·QSS + w₂·AIS + w₃·RES + w₄·SI + w₅·UXS

All benchmarks performed on IBM Quantum Cloud hardware. Results represent typical performance; individual results may vary based on hardware calibration, queue conditions, and circuit complexity.
