Optimal quantum multi-parameter estimation with few-photon states

Abstract

We report on the experimental demonstration and characterisation of the “tetrahedron state”, the optimal four-photon state for simultaneous estimation of all parameters describing a rotation. We propose a follow-up experiment to create the optimal two-photon state for this task.

Generating a 4-photon tetrahedron state: toward simultaneous super-sensitivity to non-commuting rotations

Hugo Ferretti, Y. Batuhan Yilmaz, Kent Bonsma-Fisher +5 more

It is often thought that the super-sensitivity of a quantum state to an observable comes at the cost of a decreased sensitivity to other non-commuting observables. For example, a squeezed state squeezed in position quadrature is super-sensitive to position displacements, but very insensitive to momentum displacements. This misconception was cleared with the introduction of the compass state [ Nature 412 , 712 ( 2001 ) 10.1038/35089017 ], a quantum state equally super-sensitive to displacements in position and momentum. When looking at quantum states used to measure spin rotations, N 00 N states are known to be more advantageous than classical methods as long as they are aligned to the rotation axis. When considering the estimation of a rotation with unknown direction and amplitude, a certain class of states stands out with interesting properties. These states are equally sensitive to rotations around any axis, are second-order unpolarized, and can possess the rotational properties of Platonic solids in particular dimensions. Importantly, these states are optimal for simultaneously estimating the three parameters describing a rotation. In the asymptotic limit, estimating all d parameters describing a transformation simultaneously rather than sequentially can lead to a reduction of the appropriately weighted sum of the measured parameters’ variances by a factor of d . We report the experimental creation and characterization of the lowest-dimensional such state, which we call the “tetrahedron state” due to its tetrahedral symmetry. This tetrahedron state is created in the symmetric subspace of four optical photons’ polarization in a single spatial and temporal mode, which behaves as a spin-2 particle. While imperfections due to the hardware limited the performance of our method, ongoing technological advances will enable this method to generate states which out-perform any other existing strategy in per-photon comparisons.

Quantum-Enhanced Rotation Sensing

Rotation measurements underlie many physical tasks. Specially-designed quantum states dramatically enhance sensitivities when simultaneously estimating multiple rotation parameters. Creating and detecting these states enables useful quantum devices.

Quantum parameter estimation using multi-mode Gaussian states

Dominik Šafránek, Antony R. Lee, Ivette Fuentes

Gaussian states are of increasing interest in the estimation of physical parameters because they are easy to prepare and manipulate in experiments. In this article, we derive formulae for the optimal estimation of parameters using two- and multi-mode Gaussian states. As an application of our result, we derive the optimal Gaussian probe states for the estimation of the parameter characterizing a one-mode squeezing channel.

Multi-parameter two-photon polarimetry at the quantum limit

Joseph Niblo, Luca Maggio, Russell M. J. Brooks +3 more

Photonic quantum metrology has demonstrated advantages in precision and resource efficiency for a wide range of applications, with several schemes approaching the fundamental quantum Cramér-Rao precision bound (QCRB). However, the intrinsic incompatibility of quantum measurements represents a hurdle in extending these advantages to the simultaneous estimation of multiple parameters. In this paper, we present an experimental protocol approaching the QCRB simultaneously in two polarisation parameters, across a wide range of the parameter space, with as few as $\sim 200$ photon pairs, offering advantages for polarimetric sensing for dim sources such as in X-ray astronomy or photosensitive samples.

We demonstrate the quantum-limited simultaneous estimation of the timing centroid, offset, and intensity imbalance of an incoherent mixture of two single-photon level pulses. Our measurement saturates the quantum Cramér-Rao lower bound.
