Homological Thresholds in Randomly Monitored Quantum Error-Correcting Codes
A new arXiv paper studies how homological thresholds in quantum error-correcting codes behave under random projective measurements. It treats those measurements as a shared model for monitoring, inference, and decoding in highly entangled states. The work connects this to measurement-induced critical phenomena and open questions in disordered systems.

If this mapping holds beyond the specific codes studied, near-term experiments could use small simulations to identify measurement schedules that keep a logical qubit above the homological threshold.
The paper explicitly links random projective measurements to decoding and critical behavior; a threshold expressed in terms of measurement dynamics would let existing code architectures estimate safe monitoring rates before full fault-tolerance is available.
