Phys.org February 2, 2024 Integrated quantum photonics has enabled the generation, manipulation, and detection of quantum states of light with steadily increasing scale and complexity levels. The exploration of on-chip integration has accumulated substantial progresses in recent years toward the realization of low-cost, large-scale quantum photonic circuits. Researchers in China reviewed the underlying mechanism and discuss state-of-the-art SFWM on-chip quantum light sources fabricated with various structures and materials on chip. They enumerated the most appealing applications of on-chip SFWM such as heralding single-photon source, entangled photon source, and system-level integration… read more. Open Access TECHNICAL ARTICLE

Physicists mix classical light with half a photon on a qubit
Phys.org August 31, 2021 An international team of researcher (Russia, UK) theoretically considered wave mixing under the irradiation of a single qubit by two photon fields. The first signal was a classical monochromatic drive, while the second one was a nonclassical light. They addressed two examples of a nonclassical light: (i) a broadband squeezed light and (ii) a periodically excited quantum superposition of Fock states with 0 and 1 photons. The mixing of classical and nonclassical photon fields gives rise to side peaks due to the elastic multiphoton scattering. They showed that a side peaks structure is distinct from the […]
