“…Among solid-state candidates, some promising ones are epitaxy grown QDs, color centers in diamond and solids like SiC, and rare-earth defects in glasses and crystals. As a versatile platform for photonic-state engineering, SFWM stands out as a unique resource for executing a broad class of quantum phenomena in a fiber-optic format [165,166].…”

“…Advanced methods of fiber-dispersion management, on the other hand, may prove instrumental for entanglement-time engineering [166]. As one of the recent trends, FWM with cross-polarized pump and sidebands finds growing use as a powerful resource of quantum entanglement, enabling creation of efficient fiber-optic sources of strongly antibunching heralded single photons [165] and high-brightness entangled photon pairs [166].…”

2022 Roadmap on integrated quantum photonics

Integrated photonics will play a key role in quantum systems as they grow from few-qubit prototypes to tens of thousands of qubits. The underlying optical quantum technologies can only be realized through the integration of these components onto quantum photonic integrated circuits (QPICs) with accompanying electronics. In the last decade, remarkable advances in quantum photonic integration have enabled table-top experiments to be scaled down to prototype chips with improvements in efficiency, robustness, and key performance metrics. These advances have enabled integrated quantum photonic technologies combining up to 650 optical and electrical components onto a single chip that are capable of programmable quantum information processing, chip-to-chip networking, hybrid quantum system integration, and high-speed communications. In this roadmap article, we highlight the status, current and future challenges, and emerging technologies in several key research areas in integrated quantum photonics, including photonic platforms, quantum and classical light sources, quantum frequency conversion, integrated detectors, and applications in computing, communications, and sensing. With advances in materials, photonic design architectures, fabrication and integration processes, packaging, and testing and benchmarking, in the next decade we can expect a transition from single- and few-function prototypes to large-scale integration of multi-functional and reconfigurable devices that will have a transformative impact on quantum information science and engineering.

“…As any long-distance quantum network requires fibers, a fiber-based source that could be directly spliced to the existing fiber network is desirable 8 , 11 . In this regard, silica-core fibers have attracted considerable attention due to the simplicity of their implementation 12 – 16 . Photon-pair generation using photonic crystal fibers (PCF) 17 , dispersion-shifted fibers 18 , 19 , step-index multimode optical fibers (MMF) 20 , graded-index MMF 21 , and birefringent fibers 22 has been reported as well.…”

We experimentally demonstrate frequency non-degenerate photon-pair generation via spontaneous four-wave mixing from a novel CS2-filled microstructured optical fiber. CS2 has high nonlinearity, narrow Raman lines, a broad transmission spectrum, and also has a large index contrast with the microstructured silica fiber. We can achieve phase matching over a large spectral range by tuning the pump wavelength, allowing the generation of idler photons in the infrared region, which is suitable for applications in quantum spectroscopy. Moreover, we demonstrate a coincidence-to-accidental ratio of larger than 90 and a pair generation efficiency of about $$10^{-2}$$ 10 - 2 per pump pulse, which shows the viability of this fiber-based platform as a photon-pair source for quantum technology applications.

“…It is essential that these sources generate photons not only in the correct state for the needed application, but also at wavelengths for optimal detection with the currently available single-photon detectors (SPD). The development and implementation of light sources based on non-linear optics with engineered generation of photon pairs has greatly benefited from photonic crystal fibers (PCF) [9][10][11][12]. PCF can be fabricated with highly tailored dispersion profiles, allowing for a precise control in the generation of non-linear effects such as four-wave mixing.…”

The generation of photon-pairs with controllable spectral correlations is crucial in quantum photonics. Here we present the design of a photonic crystal fiber to generate widely-spaced four-wave mixing bands with spectral correlations that can be tuned through the thermo-optic effect after being infiltrated with heavy water. We present a theoretical study of the purity of the signal and idler photons generated as a function of temperature, pump spectral linewidth and the length of the fiber.
