Abstract

A double homodyne measurement implements phase estimation for arbitrary phase values, without prior information, optimising precision for path-symmetric probe states with defined photon number. We demonstrated the method’s precision and accuracy experimentally, using single-photon probes.

Optimal phase estimation with photon-number difference measurement using twin-Fock states of light*

Jia-Min Xu, J. Z. Wang, A. X. Chen +2 more

Quantum phase measurement with multiphoton twin-Fock states has been shown to be optimal for detecting equal numbers of photons at the output ports of a Mach–Zehnder interferometer (i.e., the so-called single-fringe detection), since the phase sensitivity can saturate the quantum Cramér–Rao lower bound at certain values of phase shift. Here we report a further step to achieve a global phase estimation at the Heisenberg limit by detecting the particle-number difference (i.e., the J ^ z measurement). We show the role of experimental imperfections on the ultimate estimation precision with the six-photon twin-Fock state of light. Our results show that both the precision and the sensing region of the J ^ z measurement are better than those of the single-fringe detection, due to combined contributions of the measurement outcomes. We numerically simulate the phase estimation protocol using an asymptotically unbiased maximum likelihood estimator.

Homodyne detection is optimal for quantum interferometry with path-entangled coherent states

Z. M. McIntyre, W. A. Coish

The authors propose the use of homodyne detection to detect phase shifts and show that this method is optimal for path-entangled coherent states. This is notable because homodyne measurements do not require photon counting, and the resulting sensitivity is independent of the value of the phase shift itself.

Single-photon-added coherent states: estimation of parameters and fidelity of the optical homodyne detection

Sergey N. Filippov, Vladimir I. Man’ko, A S Coelho +2 more

The travelling modes of single-photon-added coherent states (SPACS) are characterized by using optical homodyne tomography. Given a set of experimentally measured quadrature distributions, we estimate parameters of the state and also extract information about the detector efficiency. The method used is minimal distance estimation between theoretical and experimental quantities, which additionally allows to evaluate the precision of the estimated parameters. Given the experimental data, we also estimate the lower and upper bounds on fidelity. The results are believed to encourage a more precise engineering and detection of SPACS.

Two-photon phase-sensing with single-photon detection

Panagiotis Vergyris, Charles Babin, Raphael Nold +6 more

Path-entangled multi-photon states allow optical phase-sensing beyond the shot-noise limit, provided that an efficient parity measurement can be implemented. Realizing this experimentally is technologically demanding, as it requires coincident single-photon detection proportional to the number of photons involved, which represents a severe challenge for achieving a practical quantum advantage over classical methods. Here, we exploit advanced quantum state engineering based on superposing two photon-pair creation events to realize a new approach that bypasses this issue. In particular, optical phase shifts are probed with a two-photon quantum state whose information is subsequently effectively transferred to a single-photon state. Notably, without any multiphoton detection, we infer phase shifts by measuring the average intensity of the single-photon beam on a photodiode, in analogy to standard classical measurements. Importantly, our approach maintains the quantum advantage: twice as many interference fringes are observed for the same phase shift, corresponding to N = 2 path-entangled photons. Our results demonstrate that the advantages of quantum-enhanced phase sensing can be fully exploited in standard intensity measurements, paving the way toward resource-efficient and practical quantum optical metrology.

Experimental Phase Estimation Enhanced by Machine Learning

Alessandro Lumino, Emanuele Polino, Adil S. Rab +4 more

Phase estimation has applications from quantum imaging to gravitational-wave detection. In areas such as biological-system sampling or quantum metrology, it is crucial to optimally acquire information from a very limited number of probes. To address this need, the authors describe and experimentally verify a machine-learning method for optimal adaptive single-photon phase estimation based on a small number of trials. This approach could be used to optimize quantum metrology protocols, and can be extended to general multiparameter scenarios.

Interferometric binary phase estimations

Simone Roncallo, Xi Lu, Lorenzo Maccone

We propose an interferometric scheme where each photon returns one bit of the binary expansion of an unknown phase. It sets up a method for estimating the phase value at arbitrary uncertainty. This strategy is global, since it requires no prior information, and it achieves the Heisenberg bound independently of the output statistics. We provide simulations and a characterization of this architecture.
