Subject Keyword: 020600 Quantum Physics
Language: eng
Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/84575
Description: We derive, and experimentally demonstrate, an interferometric scheme for unambiguous phase estimation with precision scaling at the Heisenberg limit that does not require adaptive measurements. That i ... More

Identifier: http://hdl.handle.net/1959.14/85357
Description: We present the theory of how to achieve phase measurements with the minimum possible variance in ways that are readily implementable with current experimental techniques. Measurements whose statistics ... More
