Abstract

We demonstrate a scalable, low-loss fiber-based frequency multiplexed single-photon source based on efficient parametric frequency conversion. We achieve a record count rate of 4.6 × 104 multiplexed photons with a low (2)(0) of 0.07.

Frequency multiplexing for quasi-deterministic heralded single-photon sources

Chaitali Joshi, Alessandro Farsi, Stéphane Clemmen +2 more

Abstract Parametric single-photon sources are well suited for large-scale quantum networks due to their potential for photonic integration. Active multiplexing of photons can overcome the intrinsically probabilistic nature of these sources, resulting in near-deterministic operation. However, previous implementations using spatial and temporal multiplexing scale unfavorably due to rapidly increasing switching losses. Here, we break this limitation via frequency multiplexing in which switching losses remain fixed irrespective of the number of multiplexed modes. We use low-noise optical frequency conversion for efficient frequency switching and demonstrate multiplexing of three modes. We achieve a generation rate of 4.6 × 104 photons per second with an ultra-low g(2)(0) = 0.07 indicating high single-photon purity. Our scalable, all-fiber multiplexing system has a total loss of just 1.3 dB, such that the 4.8 dB multiplexing enhancement markedly overcomes switching loss. Our approach offers a promising path to creating a deterministic photon source on an integrated chip-based platform.

Pure Single Photons From Scalable Frequency Multiplexing

T. Hiemstra, T.F. Parker, P. Humphreys +7 more

We demonstrate multiphoton interference using a resource-efficient frequency multiplexing scheme, suitable for quantum information applications that demand multiple indistinguishable and pure single photons. In our source, frequency-correlated photon pairs are generated over a wide range of frequencies by pulsed parametric down conversion. Indistinguishable single photons of a predetermined frequency are prepared using frequency-resolved detection of one photon to control an electro-optic frequency shift applied to its partner. Measured photon statistics show multiplexing increases the probability of delivering a single photon, without a corresponding increase to multiphoton events. Interference of consecutive outputs is used to bound the modal purity and demonstrate the nonclassical nature of the emitted light.

Singly Resonant Frequency Conversion for Manipulation of a Frequency-Multiplexed Single Photon

Rikizo Ikuta, Masayo Yokota, Toshiki Kobayashi +2 more

Optical frequency conversion is an indispensable technology in modern science and engineering. In particular, recent demand in the field of quantum information processing requires an efficient frequency conversion of a single photon which has quantum information [1], [2] for realizing quantum internet to interconnect various quantum systems. In conventional experiments, such a quantum frequency conversion (QFC) assumes an input of photons at a single frequency mode. However, when we look at frequency-multiplexed quantum communication [3], [4], the QFC will need to accommodate the frequency-multiplexed manner such that it can convert only photons in a target frequency mode from densely frequency-multiplexed input to any desired frequency mode. For this purpose, we construct an optical frequency converter inside a cavity only for the converted mode, which we call optical frequency tweezers [5].

All-fiber multiplexed source of high-purity single photons

Robert J. A. Francis-Jones, Rowan A. Hoggarth, Peter J. Mosley

Single-photon sources based on spontaneous photon-pair generation have enabled pioneering experiments in quantum physics. However, next-generation photonic quantum technologies require higher generation probabilities of photons in well-controlled pure states capable of high-visibility interference. We have harnessed bespoke fiber technology to develop virtually alignment-free sources that deliver high-purity heralded single photons in telecoms single-mode fiber. The resulting access to low-loss optical delay enabled us to actively route the heralded output from two almost identical sources to enhance the delivery probability of single photons relative to one individual source. Our results indicate how the scale of photonic quantum technologies might be increased via guided-wave multiplexing of high-purity photons.
