Abstract

We propose two different setups to generate single photons on demand using an atom in front of a mirror, along with either a beam splitter or a tunable coupling. We show that photon-generation efficiency of $\ensuremath{\sim}99%$ is straightforward to achieve. The proposed schemes are simple and easily tunable in frequency. The operation is relatively insensitive to dephasing and can be easily extended to generate correlated pairs of photons. They can also, in principle, be used to generate any photonic qubit of the form $\ensuremath{\mu}\left|0\right\ensuremath{\rangle}+\ensuremath{\nu}\left|1\right\ensuremath{\rangle}$ in arbitrary wave packets, making them very attractive for quantum communication applications.

Ultraviolet single-photons on demand and entanglement of photons with a large frequency difference

Ying Wu, M. G. Payne, E. W. Hagley +1 more

We investigate an efficient scheme for generating ultraviolet single-photons $(\ensuremath{\sim}300\phantom{\rule{0.3em}{0ex}}\mathrm{nm})$. The scheme combines the highly efficient single-photon four-wave mixing scheme and fast developing quantum dot single-photons on demand source technology. We show that near maximum, entanglement between two well matched ultraslowly propagating single-photon wave packets can be achieved. This study may lead to research and development opportunities in highly efficient entanglement schemes using photons of very large frequency difference, quantum information processing, and single-photon metrology and single-photon counting sensors in the uv spectra region.

On-Demand Microwave Generator of Shaped Single Photons

P. Forn-Díaz, Christopher Warren, C. W. Sandbo Chang +2 more

Single photons are expected to play a key role in tomorrow's quantum communication networks, owing to the robustness of photonic quantum states and their ability to travel long distances. This study demonstrates a generator that can give individual photons a desired ``shape'', which can increase their efficiency when used in a quantum network. Here the emission of an artificial atom (a superconducting circuit) is controlled by manipulating quantum vacuum fluctuations on nanosecond timescales. This tunable coupling principle could also see use in controlling quantum interactions in a variety of applications beyond single-photon generation.

Tunable Microwave Single-Photon Source Based on Transmon Qubit with High Efficiency

Yu Zhou, Zhihui Peng, Yuta Horiuchi +2 more

Single-photon sources are of great interest because they are key elements in different promising applications of quantum technologies. Here we demonstrate a highly efficient tunable on-demand microwave single-photon source based on a transmon qubit with an intrinsic emission efficiency above $98\mathrm{%}$. The high efficiency ensures a negligible pure dephasing rate and the necessary conditions for generation of indistinguishable photons. We provide an extended discussion and analysis of the efficiency of the photon generation. To further experimentally confirm the single-photon property of the source, correlation functions of the emission field are also measured using linear detectors with a GPU-enhanced signal-processing technique. Our results experimentally demonstrate that frequency tunability and negligible pure dephasing rate can be achieved simultaneously and show that such a tunable single-photon source can be good for various practical applications in quantum communication, simulations and information processing in the microwave regime.

High nonclassical correlations of large-bandwidth photon pairs generated in warm atomic vapor

J Mika, L. Slodička

Abstract Generation of nonclassical light suitable for interaction with atoms corresponds to a crucial goal pursued across the broad quantum optics community. We present the generation of nonclassical photon pairs using the process of spontaneous four-wave mixing in warm atomic vapor with an unprecedentedly high degree of nonclassical photon correlations. We show how the unique combination of excitation of atoms in the proximity of the vapor cell viewport, single excitation laser beam, double-Λ energy level scheme, auxiliary optical pumping, and particular optical filtering setups, allow for the spectral bandwidth of generated nonclassical light fields of up to 560 ± 20 MHz and low two-photon noise. We provide a quantitative analysis of particular noise mechanisms which set technological and fundamental limits on the observable photon correlations. The overall technological simplicity of the presented scheme together with the availability of spectrally matched quantum memories implementable with warm atomic vapors promises the feasibility of realization of GHz bandwidth on-demand nonclassical light sources and efficient quantum communication nodes.

Entanglement engineering of one-photon wave packets using a single-atom source

Klaus M. Gheri, C. Saavedra, Päivi Törmä +2 more

We propose a cavity-QED scheme for the controlled generation of sequences of entangled single-photon wave packets. A photon is created inside a cavity via an active medium, such as an atom, and decays into the continuum of radiation modes outside the cavity. Subsequent wave packets generated in this way behave as independent logical quantum bits (qubits). This and the possibility of producing maximally entangled multiqubit states suggest many applications in quantum communication.

Single and entangled photon pair generation using atomic vapors for quantum communication applications

Sumit Achar, Abhijit Kundu, Chilukoti Ashok +1 more

Significant progress has been achieved in leveraging atomic systems for the effective operation of quantum networks, which are essential for secure and long-distance quantum communication protocols. The key elements of such networks are quantum nodes that can store or generate both single and entangled photon pairs. The primary mechanisms leading to the production of single and entangled photon pairs revolve around established techniques such as parametric down-conversion, four-wave mixing, and stimulated Raman scattering. In contrast to solid-state platforms, atomic platforms offer a more controlled approach to the generation of single and entangled photon pairs, owing to the progress made in atom manipulation techniques such as trapping, cooling, and precise excitation schemes facilitated by the use of lasers. This review article delves into the techniques implemented for generating single and entangled photon pairs in atomic platforms, starting with a detailed discussion of the fundamental concepts associated with single and entangled photons and their characterization techniques. The aim is to evaluate the strengths and limitations of these methodologies and offer insights into potential applications. Additionally, the article will review the extent to which these atomic-based systems have been integrated into operational quantum communication networks.
