Process tomography via sequential measurements on a single quantum system. Physical Review A, 92(3), 1-61050-2947http://journals.aps.org/pra/abstract/10.1103/PhysRevA.92.032102http://hdl.handle.net/10204/8654Copyright: 2015 American Physical SocietyThe authors utilize a discrete (sequential) measurement protocol to investigate quantum process tomography of a single two-level quantum system, with an unknown initial state, undergoing Rabi oscillations. The ignorance of the dynamical parameters is encoded into a continuous-variable classical system, which is coupled to the two-level quantum system via a generalized Hamiltonian. This combined estimate of the quantum state and dynamical parameters is updated by using the information obtained from sequential measurements on the quantum system and, after a sufficient waiting period, faithful state monitoring and parameter determination is obtained. Numerical evidence is used to demonstrate the convergence of the state estimate to the true state of the hybrid system.enSequential measurementsSingle quantum systemTomographyArticleBassa, H., Goyal, S., Choudhary, S., Uys, H., Diósi, L., & Konrad, T.
