Non-classical correlations in optical beams offer an unprecedented opportunity for
surpassing the conventional limits of sensitivity and resolution in optical measurements and …

Abstract Two-dimensional (2D) hexagonal boron nitride (hBN), due to its extraordinary
thermal, chemical, and optical properties, has arisen as an enticing material for the research …

We review the rapid recent progress in single-photon sources based on multiplexing
multiple probabilistic photon-creation events. Such multiplexing allows higher single-photon …

Single emitters have been considered as sources of single photons in various contexts,
including cryptography, quantum computation, spectroscopy and metrology,,. The success of …

We derive the stochastic master equations, that is to say, quantum filters, and master
equations for an arbitrary quantum system probed by a continuous-mode bosonic input field …

The time-dependent Mandel Q parameter, Q (T), provides a measure of photon number
variance for a light source as a function of integration time. Here, we use Q (T) to …

The nitrogen vacancy (NV) center is the most widely studied single optical defect in diamond
with great potential for applications in quantum technologies. Development of practical …

We report on the experimental verification of quantum non-Gaussian character of a heralded
single-photon state with a positive Wigner function. We unambiguously demonstrate that the …

Quantum photonic devices require robust sources of single photons to perform basic
computational and communication protocols. Thus, develo** scalable, integrable, and …

A light source that emits single photons at well-defined times and into a well-defined mode
would be a decisive asset for quantum information processing, quantum metrology, and sub …
