Multiparameter Quantum Metrology with Bright Solitons
摘要
Abstract
A quantum metrology problem of simultaneous measurement and estimation of several phase parameters was considered in the framework of current tendencies of development of alternative navigation. The fundamental limits of both linear and nonlinear metrology were studied. The effect of losses on the accuracy of quantum metrology of several phase parameters was analyzed. A method to prepare three-mode N00N- states using atomic bright solitons was proposed.
