Physical realizations of the canonical phase measurement for the optical phase are unknown. Single-shot phase estimation, which aims to determine the phase of an optical field in a single shot, is critical in quantum information processing and metrology. Here we present a family of strategies for single-shot phase estimation of coherent states based on adaptive non-Gaussian, photon counting, measurements with coherent displacements that maximize information gain as the measurement progresses… 



Single-Shot Non-Gaussian Measurements for Optical Phase Estimation.

This work proposes and demonstrates strategies for single-shot measurements for ab initio phase estimation of coherent states that surpass the sensitivity limit of heterodyne measurement and approach the Cramer-Rao lower bound for coherent states.

Optical phase estimation via the coherent state and displaced-photon counting

We consider the phase sensing via a weak optical coherent state at quantum limit precision. A detection scheme for the phase estimation is proposed, which is inspired by the suboptimal quantum

Implementation of a canonical phase measurement with quantum feedback

An adaptive heterodyne technique with a Josephson parametric amplifier detector allows a high-precision single-shot canonical phase measurement on a one-photon wave packet, complementing near-ideal measurements of photon number or field amplitude.

Ab initio quantum-enhanced optical phase estimation using real-time feedback control

Using squeezed states of light combined with a real-time Bayesian adaptive estimation algorithm, deterministic phase estimation with a precision beyond the quantum shot noise limit is demonstrated

Phase tracking for sub-shot-noise-limited receivers

Non-conventional receivers for phase-coherent states based on non-Gaussian measurements such as photon counting surpass the sensitivity limits of shot-noise-limited coherent receivers, the quantum

Adaptive single-shot phase measurements: A semiclassical approach

The standard single-shot estimate for the phase of a single-mode pulse of light is the argument of the complex amplitude of the field. This complex amplitude can be measured by heterodyne detection,

Experimental Phase Estimation Enhanced By Machine Learning

This work implements experimentally single-photon adaptive phase estimation protocols enhanced by machine learning, showing the capability of reaching optimal precision after a small number of trials and introduces a new approach for Bayesian estimation that exhibit best performances for very low number of photons N.

Experimental optical phase measurement approaching the exact Heisenberg limit

Daryanoosh et al. demonstrate a scheme to achieve true HL phase measurement, using a combination of three techniques: entanglement, multiple samplings of the phase shift, and adaptive measurement, with precision within 4% of the Heisenberg limit.

Multi-state discrimination below the quantum noise limit at the single-photon level

The discrimination of multiple coherent states of light with sensitivities surpassing the quantum noise limit at the single-photon level under realistic conditions of loss and noise based on strategies implementing globally-optimized adaptive measurements with single photon counting and displacement operations is studied.

Adaptive single-shot phase measurements: The full quantum theory

The phase of a single-mode field can be measured in a single-shot measurement by interfering the field with an effectively classical local oscillator of known phase. The standard technique is to have
