Abstract:
The efficient circuits that enabled the programmable measurement of the discrete Wigner functions was presented. It was shown that it could be useful to compute averages of the Wigner function over various phase space domains. A programmable circuit that evaluates the Kirkwood distribution at any phase-space point was also presented. A quantum gate array that evaluates the discrete Husimi distribution was also presented.
