Quantum Estimation via a Single Sequence of Measurements with a Quantum Mixing Channel

Date/Time: Wed. 12th February 2014 15:00-16:00 - (room 1901/1902 (19th floor), National Institute of Informatics)

Speaker: Kazuya Yuasa (Department of Physics, Waseda University, Tokyo)

Estimating parameters of quantum systems (e.g., parameters in their Hamiltonians) is important from both practical and fundamental aspects. In standard strategies, parameters are estimated from the data accumulated by many independent and identical experiments: every time one performs a measurement, the system needs to be reset in a specific initial state.
