Researchers Verify and Repair Quantum Ancilla Safety Efficiently

Formal verification of quantum ancilla safety is now possible for circuits scaling to thousands of qubits, offering a complete workflow previously unavailable. This framework not only diagnoses faults but also guides repair, decomposing the verification of a register of *m* qubits into 2*m* independent checks. By decoupling verification from the underlying symbolic engine, a new avenue opens for…
