Rev. Lett. 100, 190403 (2008)]. The method enables the efficient estimation of any element of the χ matrix of a quantum process. Such elements are estimated as averages ...<br/>[Phys. Rev.

In the present contribution, an algorithm, which allows the solution of such systems, is proposed. It ...<br/>[Phys. Rev.
