Abstract

A quantum repeater is a system for long-distance quantum communication that employs quantum memory elements to mitigate optical fiber transmission losses. The multiplexed quantum memory (O. A. Collins, S. D. Jenkins, A. Kuzmich, and T. A. B. Kennedy, Phys. Rev. Lett. 98, 060502 (2007)) has been shown theoretically to reduce quantum memory time requirements. We present an initial implementation of a multiplexed quantum memory element in a cold rubidium gas. We show that it is possible to create atomic excitations in arbitrary memory element pairs and demonstrate the violation of Bell’s inequality for light fields generated during the write and read processes.

Fig. 1.

Schematic illustration of the quantum memory array, for clarity showing 10 rather than 12 elements. A cold sample of 85Rb atoms is produced in a magneto-optical trap (MOT). The atoms are addressed with laser beams whose position is controlled by an acoust-optic deflector (AOD), followed by a 10 cm focal length Fourier lens, used to map angular deflection into spatial translation. One pair of AODs mode-matches the write and read beams, determining the array element locations, while another pair collects the scattered signal and idler fields which are directed onto single photon detectors (Ds and Di , respectively) through etalon (E) and polarization filters (P). The signal(write) mode of each element is coupled into the idler(read) fiber mode with about 75% efficiency. The position of the four intersecting beams is controlled by simultaneously varying the AOD drive frequencies by means of a field-programmable gate array (FPGA). The four-wave mixing condition, k (j) w +k (j) r =k (j) s +k (j) i , is satisfied for each array element j by using telecentric scanning. The write and read light frequency shifts are compensated by additional AOMs in a double-pass configuration (DPAOM). The measured average separation between array elements is 230 µm. The two highlighted elements represent a matter qubit, in which an atomic spin-wave in one of the elements represents logical 0, and in the other logical 1, see text for details. The atomic energy level diagram shows the Raman scattering sequence of write and read laser excitation and retrieval employed in the quantum memory, where |a〉=|5s 1/2,F=2〉, |b〉=|5s 1/2,F=3〉, |c〉=|5p 1/2,F=3〉; the write field detuning Δ=10 MHz.

Measured coincidence fringes as functions of a signal phase ϕs, corresponding to array elements (7,8) (a), (5,10) (b), (7,10) (c), and (1,12) (d). Sinusoidal fits give corresponding visibilities 0.86(2), 0.81(2), 0.79(1), 0.73(3). Each data point has acquisition time 5 min. The effective repetition rate is 100 kHz, and each trial takes 1.5 µs. Error bars represent ±1 standard deviation based on photoelectron counting statistics.

Measured coincidence fringes corresponding to array elements 5 and 8, as functions of ϕs for ϕi =0°, squares and ϕi =90°, circles. The solid curves are fits by a function Csi (ϕs ,ϕi )∝1+V cos(ϕi +ϕs +ϕ 0) with visibilities V=(0.88(2), 0.83(2)) and phase offsets ϕ0=(0(1)°,5(3)°) for curves with ϕi =0° and ϕi =90°, respectively. Error bars represent ±1 standard deviation based on photoelectron counting statistics.
