💻 Phase flip error correction	📝 Phase flip error correction samples (auxiliary qubit-based syndrome extraction, automatic correction with auxiliary qubits and direct parity measurement)	N/A	Executable
💻 Magic rebirth	📝 Q# demo of Sudden death of entanglement, rebirth of magic, Cao, arXiv:2605.22603, 2026: amplitude damping of α|0ⁿ⟩+β|1ⁿ⟩ as an explicit Stinespring dilation, the magic-death, entanglement-death and magic-rebirth thresholds for n up to 8 with γₑ + γ₊ = 1 read off the environment register, a two-setting magic witness from shots, and parity-syndrome extraction of the reborn magic.
