Sub-shot-noise interferometric measurements with two-photon states

Abstract

We show by coincidence measurements of photon pairs, produced by parametric downconversion and type II phase matching, that a polarization rotation can be determined with an angle uncertainty below the standard quantum limit.

Tests of a two-photon technique for measuring polarization mode dispersion with subfemtosecond precision

Eric A. Dauler, Gregg S. Jaeger, Antoine Muller +2 more

An investigation is made of a recently introduced quantum interferometric method capable of measuring polarization mode dispersion (PMD) on sub-femtosecond scales, without the usual interferometric stability problems associated with such small time scales.The technique makes use of the extreme temporal correlation of orthogonally polarized pairs of photons produced via type-II phase-matched spontaneous parametric down-conversion.When sent into a simple polarization interferometer these photon pairs produce a sharp interference feature seen in the coincidence rate.The PMD of a given sample is determined from the shift of that interference feature as the sample is inserted into the system.The stability and resolution of this technique is shown to be below 0.2 fs.We explore how this precision is improved by reducing the length of the down-conversion crystal and increasing the spectral band pass of the system.

Sub-shot-noise interferometry with two-mode quantum states

Quentin Marolleau, Charlie Leprince, Victor Gondret +2 more

We study the feasibility of sub-shot-noise interferometry with imperfect detectors, starting from twin Fock states and two-mode squeezed vacuum states. We derive analytical expressions for the corresponding phase uncertainty. We find that one can achieve phase shift measurements below the standard quantum limit, as long as the losses are smaller than a given threshold, and that the measured phase is close enough to an optimal value. We provide our analytical formulas in a python package, accessible online.

Sub-shot-noise measurements using the beat note between quantum-correlated photon beams

J. J. Snyder, E. Giacobino, M. Ducloy +2 more

We propose a new method for optical measurements below the shot-noise limit. The method is based on detecting the beat note between the two quantum-correlated beams emitted by a nondegenerate optical parametric oscillator operating above threshold. Such a method can be used to enhance the sensitivity of light-scattering and polarization-rotation measurements.

Tunable Bell-inequality violations in parametric downconversion

Thomas E. Kiess, Yanhua H. Shih, Alexander V. Sergienko +2 more

We prepare two-photon quantum states by using type-II phase matching in parametric downconversion to exhibit an interference term of variable strength. This interference, set by the selection of bandwidth of interference filters used in front of two detectors, is of quantum origin. We document this by exhibiting Bell-inequality violations.

Analysis of Quantum Information Test-Bed by Parametric Down-Converted Photons Interference Measurement

W. To

Quantum optical experiments require all the components involved to be extremely stable relative to each other. The stability can be measured by using an interferometric experiment. A pair of coherent photons produced by parametric down-conversion could be chosen to be orthogonally polarized initially. By rotating the polarization of one of the wave packets, they can be recombined at a beam splitter such that interference will occur. Theoretically, the interference will create four terms in the wave function. Two terms with both photons going to the same detector, and two terms will have the photons each going to different detectors. However, the latter will cancel each other out, thus no photons will arrive at the two detectors simultaneously under ideal conditions. The stability Of the test-bed can then be inferred by the dependence of coincidence count on the rotation angle.

Sub-shot-noise heterodyne polarimetry

Sheng Feng, Olivier Pfister

We report an experimental demonstration of a heterodyne polarization rotation measurement with a noise floor 4.8 dB below the optical shot noise by use of classically phase-locked quantum twin beams emitted above threshold by an ultrastable type II Na:KTP cw optical parametric oscillator. We believe that this is the largest noise reduction achieved to date in optical phase-difference measurements.
