Benchmarking Quantum Instruments
Darian McLaren, Matthew A. Graydon, Ali Assem Mahmoud +1
Quantum measurements with feed-forward are crucial components of fault-tolerant quantum computers. We show how the error rate of such a measurement can be directly estimated by fit…

Stochastic errors in quantum instruments
Darian McLaren, Matthew A. Graydon, Joel J. Wallman
Fault-tolerant quantum computation requires non-destructive quantum measurements with classical feed-forward. Many experimental groups are actively working towards implementing suc…
