Blind Catalytic Quantum Error Correction: Target-State Estimation and Fidelity Recovery Without A Priori Knowledge
Blind Catalytic Quantum Error Correction (CQEC) allows quantum error correction to recover states without knowing the perfect target state beforehand. It estimates this unknown target from noisy data and then uses that estimate for correction. This solves a major problem in quantum computing where the ideal output is often unknown, making it useful for iterative algorithms.
