Abstract

We demonstrate experimentally the frequency-time entanglement of photon pairs produced in a CW-pumped quasi-phased-matched AlGaAs superlattice waveguide. A visibility of 96.0±0.7% without background subtraction has been achieved, which corresponds to the violation of the Bell inequality by 52 standard deviations.

We experimentally demonstrate time-frequency entanglement of photon pairs produced in a cw-pumped quasi-phased-matched AlGaAs superlattice waveguide, producing 8×106 pairs/s with 96.0 ± 0.7% visibility without background subtraction, highest known visibility by far in AlGaAs waveguides.

We report the first demonstration of CW-pumped correlated photon-pair generation in an AlGaAs waveguide with a coincidence-to-accidental ratio > 100. This is about two orders of magnitude greater than previously reported in AlGaAs waveguides.

Implementing two-photon interference in the frequency domain with electro-optic phase modulators

Laurent Olislager, I. Mbodji, Erik Woodhead +6 more

Frequency-entangled photons can be readily produced using parametric down-conversion. We have recently shown how such entanglement could be manipulated and measured using electro-optic phase modulators and narrow-band frequency filters, thereby leading to two-photon interference patterns in the frequency domain. Here we introduce new theoretical and experimental developments showing that this method is potentially a competitive platform for the realization of quantum communication protocols in standard telecommunication fibres. We derive a simple theoretical expression for the coincidence probabilities and use it to optimize a Bell inequality. Furthermore, we establish an equivalence between the entangled- photon scheme and a classical interference scheme. Our measurements of two-photon interference in the frequency domain yield raw visibilities in excess of 99%. We use our high quality setup to experimentally validate the theoretical predictions, and in particular we report a violation of the CH74 inequality by more than 18 standard deviations.

Violation of Bell's Inequality in 1550 nm Band without Subtraction of Accidental Coincidences

Akio Yoshizawa, Hidemi Tsuchida

A violation of Bell's inequalities using quantum entanglement indicates the nonlocality of two particles such as photons and electrons. We observe a violation of the Clauser-Horne-Shimony-Holt (CHSH) inequality, a particular Bell's inequality, in polarization-entangled photon pairs in the 1550 nm band. For photon pair generation based on spontaneous parametric down conversion, a fiber-optic two-photon interferometer with two periodically poled lithium niobate waveguides is adopted. The obtained S value of the CHSH inequality is 2.44 ±0.02 without subtraction of accidental coincidences, yielding a violation by ∼22 standard deviations in an hour. Two-photon interference with a visibility of 0.885 is also observed. If those coincidences are subtracted, the visibility becomes almost unity.

Generation of Time-Bin Entanglement in a Silicon Waveguide With Variable Channel Bandwidths

Yan Xu, Rui Wang, Meng Xue Deng +2 more

Entangled photon pairs based on silicon straight waveguides have been applied in the area of quantum information owing to the compactness of the devices and high nonlinearity of the silicon material. In order to fully take advantage of the broad emission spectrum of photon pairs for quantum-key-distribution, dense wavelength division multiplexer (DWDM) is often required. However, the relationship between the channel bandwidth of DWDM and the two-photon interference visibility remains unambiguous, in which the high visibility of quantum interference fundamentally reduces quantum bit error rate in quantum-key-distribution system. In this paper, time-bin entangled photon pairs with a raw visibility of 94.3% ± 3.3% are generated in a silicon chip with a channel bandwidth of 0.1 nm, showing a violation of Bell’s inequality by more than three standard deviations, and a fidelity of 0.942 ± 0.02 is obtained by quantum state tomography. Applying variable channel bandwidths, the corresponding two-photon interference visibilities are measured, fitting well with the theoretical model incorporating multiple parameters such as optical loss, dark count probability, and averaged photon-pair number in DWDM channel.
