Abstract

We demonstrate frequency-conversion of quantum dot photons to the telecom C-band enabled by a custom-built, tunable mid-infrared laser. We achieve high brightness while preserving the photons’ coherence properties, outperforming state-of-the-art solid-state emitters at telecom wavelengths.

A bright source of telecom single photons based on quantum frequency conversion

Christopher L. Morrison, Markus Rambach, Zhe Xian Koong +10 more

On-demand indistinguishable single-photon sources are essential for quantum networking and communication. Semiconductor quantum dots are among the most promising candidates, but their typical emission wavelength renders them unsuitable for use in fiber networks. Here, we present quantum frequency conversion of near-infrared photons from a bright quantum dot to the telecommunication C-band, allowing integration with existing fiber architectures. We use a custom-built, tunable 2400 nm seed laser to convert single photons from 942 nm to 1550 nm in a difference-frequency generation process. We achieve an end-to-end conversion efficiency of ≃35%, demonstrate count rates approaching 1 MHz at 1550 nm with g(2)(0)=0.043(1), and achieve Hong-Ou-Mandel (HOM) visibilities of 60%. We expect this scheme to be preferable to quantum dot sources directly emitting at telecom wavelengths for fiber-based quantum networking.

An Absolutely Referenced, Tunable Mid-IR Source For Long-Distance Quantum Networking

Saeed Pegahan, Adam T. Heiniger, Katharina Predehl +6 more

SummaryScalable quantum communication relies on transferring entangled photons (flying qubits) between distant nodes via fiber networks in the telecom C-band to minimize fiber loss. Quantum frequency conversion bridges VIS/NIR photon emission from stationary qubits to telecom wavelengths, with laser synchronization via optical frequency combs ensuring precise wavelength matching. Using an absolutely referenced, tunable OPO and coherent frequency conversion, we demonstrate a setup for matching the photon wavelengths of Ca⁺ ions and SnV centers, transmitted over a 14 km fiber link.

Purifying quantum-dot light in a coherent frequency interface

Fabrizio Chiriano, Christopher L. Morrison, Joseph Ho +2 more

Abstract Quantum networks typically operate in the telecom wavelengths to take advantage of low-loss transmission in optical fibres. However, bright quantum dots (QDs) emitting highly indistinguishable quantum states of light, such as InGaAs QDs, often emit photons in the near infrared thus necessitating frequency conversion (FC) to the telecom band. Furthermore, the signal quality of quantum emissions is crucial for the effective performance of these networks. In this work we report a method for simultaneously implementing spectral purification and frequency shifting of single photons from QD sources to the c-band in a periodically poled lithium niobate waveguide. We consider difference frequency generation in the counter-propagating configuration to implement FC with the output emission bandwidth in units of GHz. Our approach establishes a clear path to integrating high-performance single-emitter sources in a hybrid quantum network.

Quantum key distribution with a bright telecom wavelength quantum dot single-photon source

Christopher L. Morrison, Francesco Graffitti, Zhe Xian Koong +4 more

A source of bright and pure single photons is an essential tool for photonic quantum technologies, predicted to enable secure communication and networking. Self-assembled quantum dots are among the leading candidates to realise such a source. The currently highest-performing quantum dots emit at wavelengths unsuitable for fibre transmission, with telecom quantum dots lagging in performance. An intermediate step is to use quantum frequency conversion. Here we report to our knowledge the brightest quantum dot based source of telecom photons by frequency converting a near-infrared quantum dot embedded in a micropillar cavity to the telecom C-band. In a single-photon BB84 protocol, this source is capable of producing asymptotic keys rates of 1 kbps at over 150 km of optical fibre.

Quantum frequency conversion of visible single photons from a quantum dot to a telecom band

Andreas Lenhard, Sebastian Zaske, Christian Kessler +8 more

Establishing a network of quantum systems will be based on single photons as flying qubits. For a long range transmission, wavelengths in the low-loss telecom bands will be necessary. As such a network may consist of dissimilar systems emitting at different wavelengths, an interface will be required converting the photons to the telecom band without disturbing the single photon quantum properties. We here demonstrate frequency down-conversion of single photons from a quantum dot and prove the preservation of the single photon character [1].
