We demonstrate optical coherence tomography based on an SU (1, 1) nonlinear
interferometer with high-gain parametric downconversion. For imaging and sensing …

The possibility to manage and control spectral and spatial properties of optical-terahertz
nonclassical fields generated in strongly nondegenerate parametric down-conversion is …

We study conditions for the generation of strongly correlated photons of two extremely
different frequency ranges, optical and terahertz, via the spontaneous parametric down …

Statistical distributions of the analog readings of an antenna-coupled THz superconducting
bolometer were measured and analyzed under a special type of irradiation by low-energy …

Floodlight quantum key distribution (FL-QKD) is a new QKD protocol that can achieve a 2
Gbps secret key rate (SKR) in a 50 km fiber link without multiplexing technology [Q. Zhuang …

The conditions for the generation and detection of quantum-correlated pairs of optical and
terahertz photons in the process of strongly frequency-nondegenerate parametric down …

The effect of the structure of angular modes of an optical–terahertz biphoton field appearing

We study the statistical distributions of the output signals of a superconducting hot-electron
bolometer (HEB) detector exposed to weak photon pulses of 1 THz (terahertz) frequency …

The second-order correlation function which characterizes the quantum correlation between
the optical and terahertz photons generated under spontaneous parametric down …

Quantum-optical technologies based on parametric light down-conversion are not yet
applied in the terahertz frequency range. This is owing to the complexity of detecting single …
