Nonideal quantum detectors in Bayesian formalism
نویسنده
چکیده
The Bayesian formalism for a continuous measurement of solid-state qubits is extended to a model which takes into account several factors of the detector nonideality. In particular, we consider additional classical output and backaction noises ~with finite correlation!, together with quantum-limited output and backaction noises, and take into account possible asymmetry of the detector coupling. The formalism is first derived for a single qubit and then generalized to the measurement of entangled qubits.

Heisenberg-limited interferometric measurements with quantum correlated photons: influence of decorrelation and photon statistics
The feasibility of a Heisenberg limited phase measurement using a MachZehnder interferometer fed with twin photon correlated light is investigated. To take advantage of the Heisenberg limit, 1/N , for the phase sensitivity, one wants the number of correlated photons, N , to be high. This favors the use of parametric oscillation rather than the weaker but better correlated source given by parame...
متن کاملNoisy quantum measurement of solid-state qubits: Bayesian approach
We discuss a recently developed formalism which describes the quantum evolution of a solid-state qubit due to its continuous measurement. In contrast to the conventional ensembleaveraged formalism, it takes into account the measurement record and therefore is able to consider individual realizations of the measurement process. The formalism provides testable experimental predictions and can be ...
متن کاملNoisy quantum measurement of solid-state qubits
The quantum evolution of an individual solid-state qubit during the process of its continuous measurement can be described by the recently developed Bayesian formalism. In contrast to the conventional ensemble-averaged formalism, it takes into account the measurement record (in a way similar to the standard Bayesian analysis) and therefore is able to consider individual realizations of the meas...
متن کاملQuantum Zeno stabilization in weak continuous measurement of two qubits
We have studied quantum coherent oscillations of two qubits under continuous measurement by a symmetrically coupled mesoscopic detector. The analysis is based on a Bayesian formalism that is applicable to individual quantum systems. Measurement continuously collapses the two-qubit system to one of the subspaces of the Bell basis. For a detector with linear response this corresponds to measureme...
متن کاملTesting for multipartite quantum nonlocality using functional bell inequalities.
We show that arbitrary functions of continuous variables, e.g., position and momentum, can be used to generate tests that distinguish quantum theory from local hidden variable theories. By optimizing these functions, we obtain more robust violations of local causality than obtained previously. We analytically calculate the optimal function and include the effect of nonideal detectors and noise,...
