Package 24 — Qubit decoherence as UTAC threshold system (GenesisAeon Entropy Atlas)

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

Domain	Package	Γ	Note
Solar flare magnetic field	P21	0.014	Ultra-sensitive
Cygnus X-1 jet	P17	0.046	Hair-trigger
Qubit decoherence (T2)	P24	0.050	← quantum-genesis
Apoptosis ATP threshold	P25	0.090	Cellular critical
Amazon rainforest	P19	0.116	Ecological fragile
Neural criticality / AMOC	P18/P20	0.251	Homeostatic universal

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:

Symbol	Meaning
C	Off-diagonal density matrix coherence |ρ₀₁|
R	Proximity of error rate to QEC threshold (resonance at p_th)
E	Logical vs. physical error rate ratio (emergent QEC benefit)
P	Entropy of T1 distribution / logical depth efficiency

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.

# 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

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).
