Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

Communication is an integral part of human life. Today, optical pulses are the preferred
information carriers for long-distance communication. The exponential growth in data leads …

High time-bandwidth product signal and idler pulses comprised of independent identically
distributed two-mode squeezed vacuum (TMSV) states are readily produced by …

The achievable rate of information transfer in optical communications is determined by the
physical properties of the communication channel, such as the intrinsic channel noise …

Quantum receivers aim to effectively navigate the vast quantum-state space to endow
quantum information processing capabilities unmatched by classical receivers. To date, only …

Discrimination of coherent states beyond the standard quantum limit (SQL) is an important
task not only for quantum information processing but also for optical coherent …

The discrimination of two nonorthogonal states is a fundamental element for secure and
efficient communication. Quantum measurements of nonorthogonal coherent states can …

In this work we design a procedure to estimate the minimum size beyond which a system is
amenable to a classical-like description, ie, a description based on representative points in …

Quantum enhanced receivers are endowed with resources to achieve higher sensitivities
than conventional technologies. For application in optical communications, they provide …

Physical realizations of the canonical phase measurement for the optical phase are
unknown. Single-shot phase estimation, which aims to determine the phase of an optical …
