Physical Review A

Spatial separation of collinearly emitted broadband frequency-correlated photon pairs

Abstract

The authors demonstrate the efficient separation of broadband frequency-entangled photon pairs generated in the same spatial and polarization mode. Entangled photons with a broad bandwidth of 90 nm are successfully separated using time-reversed Hong-Ou-Mandel interference.

Polarization Entanglement by Time-Reversed Hong-Ou-Mandel Interference

Yuanyuan Chen, Sebastian Ecker, Sören Wengerowsky +4 more

Sources of entanglement are an enabling resource in quantum technology, and pushing the limits of generation rate and quality of entanglement is a necessary prerequisite towards practical applications. Here, we present an ultrabright source of polarization-entangled photon pairs based on time-reversed Hong-Ou-Mandel interference. By superimposing four pair-creation possibilities on a polarization beam splitter, pairs of identical photons are separated into two spatial modes without the usual requirement for wavelength distinguishability or noncollinear emission angles. Our source yields high-fidelity polarization entanglement and high pair-generation rates without any requirement for active interferometric stabilization, which makes it an ideal candidate for a variety of applications, in particular those requiring indistinguishable photons.

Poled-fiber source of broadband polarization-entangled photon pairs

E. Y. Zhu, Zhenzhou Tang, Li Qian +7 more

We demonstrate broadband polarization-entangled photon pair generation in a poled fiber phase matched for Type II downconversion in the 1.5 μm telecom band. Even with signal-idler separation greater than 100 nm, we observe fringe visibilities greater than 97% and tangle greater than 0.8. A Hong-Ou-Mandel interference experiment is also used to experimentally confirm the broadband nature of the entanglement.

Two-photon experiments in the frequency domain

I. Mbodji, Laurent Olislager, Erik Woodhead +7 more

We report on the study of two-photon interference in the frequency domain. Bell and Hong-Ou-Mandel experiments are investigated. These experiments involve the manipulation of photons in the frequency domain, using off-the-shelf telecommunication components such as electro-optic phase modulators and narrow-band frequency filters. In the first experiment, photon pairs entangled in frequency are created and separated. Each photon is then directed through an independent electro-optic phase modulator. Variation of the radio-frequency parameters of the modulation gives rise to a well-controlled Bessel-shape two-photon interference pattern in the frequency domain. This is efficiently measured with narrow-band frequency filters and superconducting single photon detectors. Experimental measurements exhibit high visibilities (over 99 percent both for net and raw visibilities) and allow the (theoretically proven) optimal violation of a Bell inequality for our setup (by more than 18 standard deviations). The second experiment is a Hong-Ou-Mandel experiment in the frequency domain. We show that a grating (spatial domain) or a phase modulator (temporal domain) can be seen as a frequency beam splitter. A broadband spectrum of photon pairs is divided into two interleaved frequency combs, each one used as an independent input to this acting beam splitter. A theoretical calculation shows clear photon anti-bunching behavior.

Pure-State Photon-Pair Source with a Long Coherence Time for Large-Scale Quantum Information Processing

Bo Li, Yu-Huai Li, Yuan Wen Cao +2 more

This study presents an experimental technique to tackle technical obstacles in generating photon pairs in pure states with extended coherence times. Such photon sources are vital for large-scale quantum information processing. The authors successfully eliminate the frequency correlation of parametric photons using optimal filtering, which enables high-quality Hong-Ou-Mandel interference between two photon sources. This breakthrough has promising practical applications in quantum science and can facilitate engineering solutions for long-distance quantum interference.

We present a high quality degenerate source of polarization-entangled photons (0.96 ± 0.01 fidelity with a maximally entangled state). Reverse Hong-Ou-Mandel interference in an optical-fiber Sagnac loop deterministically separates the indistinguishable photons.
