Phase Sensitivity Improvement in Correlation-Enhanced Nonlinear Interferometers

چکیده
Interferometers are widely used as sensors in precision measurement. Compared with a conventional Mach–Zehnder interferometer, the sensitivity of correlation-enhanced nonlinear interferometer can break standard quantum limit. Phase plays significant role enhanced performance. In this paper, we review improvement phase estimation technologies interferometers, including SU(1,1) and SU(1,1)-SU(2) hybrid so on, applications metrology sensing networks.

Origin and removal of mixed-phase artifacts in gradient sensitivity enhanced heteronuclear single quantum correlation spectra
Here we describe phasing anomalies observed in gradient sensitivity enhanced (15)N-(1)H HSQC spectra, and analyze their origin. It is shown that, as a result of (15)N off-resonance effects, dispersive contributions to the (1)H signal become detectable, and lead to (15)N-offset dependent phase errors. Strategies that effectively suppress these artifacts are presented.
متن کاملQuantum-enhanced multiparameter estimation in multiarm interferometers
Quantum metrology is the state-of-the-art measurement technology. It uses quantum resources to enhance the sensitivity of phase estimation over that achievable by classical physics. While single parameter estimation theory has been widely investigated, much less is known about the simultaneous estimation of multiple phases, which finds key applications in imaging and sensing. In this manuscript...
متن کاملPhase and alignment noise in grating interferometers
Diffraction gratings have been proposed as core optical elements in future laser interferometric gravitational-wave detectors. In this paper, we derive equations for the coupling between alignment noise and phase noise at diffraction gratings. In comparison to a standard reflective component (mirror or beam splitter) the diffractive nature of the gratings causes an additional coupling of geomet...
متن کاملPhase measurements in Aharonov-Bohm interferometers
In this paper we address measurements of the resonant quantum transmission amplitude tQD = −i|tQD|e iαQD through a quantum dot (QD), as function of the plunger gate voltage V . Mesoscopic solid state Aharonov-Bohm interferometers (ABI) have been used to measure the “intrinsic” phase, αQD, when the QD is placed on one of the paths. In a “closed” interferometer, connected to two terminals, the el...
متن کاملSensitivity Curves for Spaceborne Gravitational Wave Interferometers
To determine whether particular sources of gravitational radiation will be detectable by a specific gravitational wave detector, it is necessary to know the sensitivity limits of the instrument. These instrumental sensitivities are often depicted ~after averaging over source position and polarization! by graphing the minimal values of the gravitational wave amplitude detectable by the instrumen...
