On its revolutionary threshold, quantum sensing is creating potentially transformative
opportunities to exploit intricate quantum mechanical phenomena in new ways to make …

This book offers a concise review of quantum radar theory. Our approach is pedagogical,
making emphasis on the physics behind the operation of a hypothetical quantum radar. We …

The recent advances in quantum information processing, sensing, and communications are
surveyed with the objective of identifying the associated knowledge gaps and formulating a …

We have built an imaging system that uses a photon's position or time-of-flight information to
image an object, while using the photon's polarization for security. This ability allows us to …

We analyze the fundamental quantum limit of the resolution of an optical imaging system
from the perspective of the detection problem of deciding whether the optical field in the …

Over the past three decades, quantum mechanics has allowed the development of
technologies that provide unconditionally secure communication. In parallel, the quantum …

Different from conventional radar systems, for the single-photon radar, a single-photon
detector acts as the receiver to detect the echo signal with only a few photons, which can be …

Higher transmission loss diminishes the performance of optical communication—be it the
rate at which classical or quantum data can be sent reliably, or the secure key generation …

We demonstrate the dependence of the squeezing and anti-squeezing factors on the seed
beam power at different pump beam noise levels. The results indicate that a seed field …

We report on a compensation characteristic of the phase shifts, originating from the cavity
detuning and phase mismatching, in the process of squeezed state generation. In the …
