Instance-optimal state certification with entangled measurements
Instance-optimal state certification with entangled measurements — original question and dated source context.
Problem statement
Given a known reference state and copies of an unknown state , distinguish from . Determine sample complexity bounds depending on the particular when joint, entangled measurements are allowed, analogous to instance-optimal results for incoherent measurements.
