Characterizing the performance of continuous-variable Gaussian quantum gates
Kunal Sharma, Mark M. Wilde · Physical Review Research · 2020
This paper studies different performance criteria to analyze how well experimental approximations of basic building blocks (quantum gates) of a continuous-variable quantum computer simulate the corresponding ideal transformations. In particular, the authors establish analytical bounds on the worst-case error in simulating ideal quantum gates, which is important to quantify the accuracy of any continuous-variable quantum computation
