The science of quantum information has arisen over the last two decades centered on the
manipulation of individual quanta of information, known as quantum bits or qubits. Quantum …

Quantum sensing has become a broad field. It is generally related with the idea of using
quantum resources to boost the performance of a number of practical tasks, including the …

The use of quantum-mechanically entangled light to illuminate objects can provide
substantial enhancements over unentangled light for detecting and imaging those objects in …

An optical transmitter irradiates a target region containing a bright thermal-noise bath in
which a low-reflectivity object might be embedded. The light received from this region is …

We present the first experimental realization of the quantum illumination protocol proposed
by Lloyd [Science 321, 1463 (2008) SCIEAS 0036-8075] and S. Tan et al.[Phys. Rev. Lett …

Superposition and entanglement, the quintessential characteristics of quantum physics,
have been shown to provide communication, computation, and sensing capabilities that go …

Characterization of quantum dynamics is a fundamental problem in quantum physics and
quantum-information science. Several methods are known which achieve this goal, namely …

The dynamics of two variants of quantum Fisher information under decoherence is
investigated from a geometrical point of view. We first derive the explicit formulas of these …

We derive a computable analytical formula for the quantum fidelity between two arbitrary
multimode Gaussian states which is simply expressed in terms of their first-and second …

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 …
