Quantum Turnstiles for Robust Measurement of Full Counting Statistics
Quantum Turnstiles for Robust Measurement of Full Counting Statistics
We present a scalable protocol for measuring full counting statistics (FCS) in experiments or tensor-network simulations. In this method, an ancilla in the middle of the system acts as a turnstile, with its phase keeping track of the time-integrated particle flux. Unlike quantum gas microscopy, the turnstile protocol faithfully captures …
