Single-photon detectors are ubiquitous in quantum information science and quantum
sensing. They are key enabling technologies for numerous scientific discoveries and …

Normalized correlation functions provide expedient means for determining the photon-
number properties of light. These higher-order moments, also called the normalized factorial …

Although heralding signals in quantum optics experiments are typically based on the
detection of exactly one photon, it has recently been theoretically shown that heralding …

Zero-photon subtraction (ZPS) is a conditional measurement process that can reduce the
mean photon number of quantum optical states without physically removing any photons …

The process of single-photon subtraction (SPS) is known to dramatically alter the properties
of certain quantum optical states. Somewhat surprisingly, subtracting zero photons can also …

Thermal radiation played a pivotal role in the preliminary development of quantum physics
where it helped resolve the apparent incongruity of the ultraviolet catastrophe. In …

It is thought that schemes for quantum imaging are fragile against realistic environments in
which the background noise is often stronger than the nonclassical signal of the imaging …

The concept of Maxwell's demon, proposed in classical physics as a means to extract work
from a thermodynamics system beyond the constraints set by the second law of …

Attenuating a quantum state using a beam splitter will introduce noise and decoherence.
Here we show that heralding techniques can be used to attenuate Schrödinger cat states …

Multiple photon addition and subtraction applied to multi-mode thermal and sub-Poissonian
fields as well as twin beams are mutually compared using one experimental setup. Twin …
