Quantum-Code Correlations Survive Two Noise Regimes
A proof finds exponential decay of conditional mutual information under weak noise and under strong noise when the buffer carries no logical operator.
Summary
A proof finds exponential decay of conditional mutual information under weak noise and under strong noise when the buffer carries no logical operator.
For normalized projector states of Z-d qLDPC stabilizer codes, the authors derive system-size-independent bounds and, on finite-dimensional lattices, a quasi-local recovery channel in the weak-noise regime. This is a mathematical stability result, not a hardware demonstration.
Why it matters
A proof finds exponential decay of conditional mutual information under weak noise and under strong noise when the buffer carries no logical operator.
Limits and context
- This is a mathematical stability result, not a hardware demonstration.
