Identifier: http://hdl.handle.net/1959.14/263720
Description: The ultimate limits to estimating a fluctuating phase imposed on an optical beam can be found using the recently derived continuous quantum Cramér-Rao bound. For Gaussian stationary statistics, and a ... More

Description: We use the quantum Fisher information to show the ultimate limit to the accuracy of measurement of a fluctuating phase with a squeezed state. This measurement accuracy is achievable using an adaptive ... More

Identifier: http://hdl.handle.net/1959.14/206362
Description: The ultimate bound to the accuracy of phase estimates is often assumed to be given by the Heisenberg limit. Recent work seemed to indicate that this bound can be violated, yielding measurements with m... More

Identifier: http://hdl.handle.net/1959.14/187170
Description: The Heisenberg limit traditionally provides a lower bound on the phase uncertainty scaling as 1/N, where N is the mean number of photons in the probe. However, this limit has a number of loopholes whi... More

Identifier: http://hdl.handle.net/1959.14/22959
Description: For any master equation which is local in time, whether Markovian, non-Markovian, of Lindblad form or not, a general procedure is given for constructing the corresponding linear map from the initial s... More
