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

Identifier: http://hdl.handle.net/1959.14/278296
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

Language: eng
Resource Type: journal article
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

Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/198241
Description: Tracking a randomly varying optical phase is a key task in metrology, with applications in optical communication. The best precision for optical-phase tracking has until now been limited by the quantu ... More

Subject Keyword: 020600 Quantum Physics
Language: eng
Resource Type: journal article
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/1959.14/312075
Description: Adaptive techniques make practical many quantum measurements that would otherwise be beyond current laboratory capabilities. For example, they allow discrimination of nonorthogonal states with a proba ... More

Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/42243
Description: We have previously [Phys. Rev. A 65, 043803 (2002)] analyzed adaptive measurements for estimating the continuously varying phase of a coherent beam, and a broadband squeezed beam. A real squeezed beam ... More
