In this article, it was shown that a certain fundamental limit applies to the accuracy of all optical rotation sensors which use laser light as a probe, and the same relationship is obtained from a spontaneous-emission noise formulation.
Abstract
We show that a certain fundamental limit applies to the accuracy of all optical rotation sensors which use laser light as a probe. We derive this fundamental rotation-rate uncertainty from the Heisenberg uncertainty relations and Glauber's minimum uncertainty states. The same relationship is obtained from a spontaneous-emission noise formulation. We present experimental data on a (nondithered) four-frequency ring laser gyroscope for which this limit is attained.

Ring-laser tests of fundamental physics and geophysics

TL;DR: In this article, the capability of ring-laser gyros for measurements of geodesic interest, including seismometry and earth tides, and for detection of other sources of non-reciprocal refractive indices, including axions and CP violation, are discussed.

Preparation, measurement and information capacity of optical quantum states

TL;DR: In this paper, the quantum noise is evaluated for various simultaneous measurements of two quadrature components: heterodyning, the beam splitter followed by two single quadratures measurements, the parametric amplifier, the (degenerate and/or nondegenerate) four-wave mixer, the Brillouin and Raman amplifiers, and the laser amplifier.

Sub-Poissonian processes in quantum optics

TL;DR: In this article, a review of methods for generating sub-Poissonian light and related concepts is presented. But the authors focus on the conceptual foundations and developments in laser theory that lead to the possibility, already demonstrated experimentally, of linewidth narrowing and sub-poissonic light generation in lasers and masers.

Quantum limitations and back action evading measurements in classical force and rotation detection

TL;DR: In this article, the authors theoretically study both the technical and fundamental quantum limitations of the sensitivity of a resonant optical gyroscope based on a high finesse optical cavity and show that the quantum back action associated with the resonantly enhanced optical cross and self-phase modulation results in the nonlinear optics-mediated standard quantum limit (SQL) of the angle random walk of the gyroometer.
