quantum-genesis

Qubit decoherence as a UTAC threshold system — Package 24 of the GenesisAeon Entropy Atlas.

Models superconducting qubit decoherence via the CREP (Coherence–Resonance–Emergence–Poetics) framework, coupling the QEC threshold theorem to the Unified Threshold Adaptive Criticality (UTAC) system.

Central result: Γ_quantum ≈ 0.050 — qubits are the most fragile UTAC system in the Entropy Atlas (just above solar magnetic flares at Γ ≈ 0.014). This quantifies why quantum computing is extraordinarily difficult: any perturbation can cross the phase boundary.

CREP Criticality Spectrum — quantum-genesis in context

Physical Mapping to UTAC

H(t)  ← coherence fraction = (1 − p_error) ∈ [0, 1]
K     ← 1.0   (perfect coherence ceiling)
H*    ← 1 − p_threshold ≈ 0.999   (QEC phase boundary)
r     ← 0.10  (coherence improvement rate per generation)
σ     ← 2.2   (universal CREP coupling)

CREP tensor components:

Phase transition: The QEC threshold at p_th ≈ 10⁻³ is the UTAC phase boundary. Below threshold → stable logical qubit. Above threshold → decoherence cascade. At threshold → information critical phase (Vijay & Lee 2026): fractional logical qubit preservation f ≈ 0.25.

Installation

pip install quantum-genesis
# or
uv add quantum-genesis

# Optional backends
pip install quantum-genesis[sim]   # stim + qiskit-ibm-runtime

Quickstart

from quantum_genesis import QuantumGenesis

qg = QuantumGenesis(t1_us=100.0)       # Google Willow reference T1

# Run 1000 QEC syndrome cycles
result = qg.run_cycle(n_syndrome_cycles=1000)
print(result)
# {'n_syndrome_cycles': 1000, 'crep': {'C': ..., 'R': ..., 'E': ..., 'P': ..., 'Gamma': 0.049...}, ...}

# Diamond interface
print(qg.get_crep_state())   # {C, R, E, P, Gamma}
print(qg.get_utac_state())   # {H, dH_dt, H_star, K_eff}
print(qg.get_phase_events()) # decoherence cascade events
print(qg.is_below_threshold())        # True
print(qg.logical_error_rate(d=7))     # surface code d=7
print(qg.gamma_quantum())             # ≈ 0.050

# Zenodo metadata record
record = qg.to_zenodo_record()

Diamond Interface Contract

All GenesisAeon packages implement this interface:

class QuantumGenesis:
    def run_cycle(self, n_syndrome_cycles: int = 1000) -> dict: ...
    def get_crep_state(self) -> dict:    # {C, R, E, P, Gamma}
    def get_utac_state(self) -> dict:    # {H, dH_dt, H_star, K_eff}
    def get_phase_events(self) -> list:  # logical error events
    def to_zenodo_record(self) -> dict:  # Zenodo-compatible metadata

Falsifiable Prediction

As T1 improves toward 1 ms (next-generation qubits), Γ_quantum will increase from 0.050 toward 0.100, placing quantum systems in the "cellular critical" range — equivalent to the apoptosis ATP threshold (Package 25). Testable against IBM Quantum roadmap milestones (public).
