Quantum algorithms for phase space tomography
Juan Pablo Paz, Augusto J. Roncaglia, Marcos Saraceno
We present efficient circuits that can be used for the phase space tomography of quantum states. The circuits evaluate individual values or selected averages of the Wigner, Kirkwoo…

A quantum gate array can be programmed to evaluate the expectation value of any operator
Juan Pablo Paz, Augusto Roncaglia
A programmable gate array is a circuit whose action is controlled by input data. In this letter we describe a special--purpose quantum circuit that can be programmed to evaluate th…
