Physical Review A

Cancellation of dispersion and temporal modulation with nonentangled frequency-correlated photons

Abstract

The observation of the so-called dispersion cancellation of paired photons is generally attributed to the presence of frequency entanglement between two frequency anticorrelated photons. In this paper, it is shown that by introducing the appropriate amount of chromatic dispersion or phase modulation between nonentangled photons, it is also possible to observe these effects. Indeed, it is found that the relevant characteristic required for the observation of dispersion cancellation or the cancellation of temporal phase modulation is the presence of certain frequency correlations between the photons and not necessarily the presence of entanglement.

Quantification of nonlocal dispersion cancellation for finite frequency entanglement

Xiao Xiang, Ruifang Dong, Baihong Li +4 more

Benefiting from the unique quantum feature of nonlocal dispersion cancellation (NDC), the strong temporal correlation of frequency-entangled photon pair source can be maintained from the unavoidable dispersive propagation. It has thus played a major role in many fiber-based quantum information applications. However, the limit of NDC due to finite frequency entanglement has not been quantified. In this study, we provide a full theoretical analysis of the NDC characteristics for the photon pairs with finite frequency entanglement. Experimental examinations were conducted by using two spontaneous parametric down-conversion photon pair sources with frequency correlation and anticorrelation properties. The excellent agreement demonstrates the fundamental limit on the minimum temporal correlation width by the nonzero two-photon spectral correlation width of the paired photons, which introduces an inevitable broadening by interaction with the dispersion in the signal path. This study provides an easily accessible tool for assessing and optimizing the NDC in various quantum information applications.

Observations of Dispersion Cancellation of Entangled Photon Pairs

Kevin A. O’Donnell

An experimental study of the dispersion cancellation occurring in frequency-entangled photon pairs is presented. The approach uses time-resolved up-conversion of the pairs, which has temporal resolution at the femtosecond level, and group-delay dispersion sensitivity of $\ensuremath{\approx}20\text{ }\text{ }{\mathrm{fs}}^{2}$ under experimental conditions. The cancellation is demonstrated with dispersion stronger than $\ifmmode\pm\else\textpm\fi{}{10}^{3}\text{ }\text{ }{\mathrm{fs}}^{2}$ in the signal ($\ensuremath{-}$) and idler ($+$) modes.

Nonlocal cancellation of multi-frequency-channel dispersion

Xiaolong Hu, Tian Zhong, Franco N. C. Wong +6 more

We present an investigation of the temporal correlation of time-energy entangled photon pairs propagating through multi-frequency-channel dispersive media, in which photon spectra spread over multiple discrete frequency channels with dispersions. We have observed more complex coincidence structures including double coincidence envelopes and dependence on frequency detuning that are absent in the single-channel case. Our results on the correlation of the time-energy photonic entanglement in dispersive media with channel divisions would impact the fields of quantum metrology and communication.

Nonlocal Cancellation of Multi-Frequency-Channel Dispersion Yields Double Coincidence Peaks

Xiaolong Hu, Xiang Mao, Jacob Mower +6 more

We have observed that temporally-correlated photon pairs, experiencing multi-frequency-channel, opposite dispersion, yield double coincidence peaks. We present and compare theoretical and experimental results.

Lack of dispersion cancellation with classical phase-sensitive light

J. D. Franson

Shapiro recently argued that nonlocal dispersion cancellation using entangled pairs of photons is essentially classical in nature, based on a comparison with a classical model in which two stationary, chaotic beams of light have phases and frequencies that are anticorrelated, which he refers to as ``phase-sensitive'' light [J. H. Shapiro, Phys. Rev. A 81, 023824 (2010)]. It is shown here that there is no physical cancellation of dispersion for classical light of that kind and Shapiro's results merely reflect the fact that identical dispersion occurs in both beams. The origin of the cross correlations between the intensities of the two beams is shown to be completely different in the classical and quantum mechanical cases.
