In the standard quantum theory, the causal order of occurrence between events is
prescribed, and must be definite. This has been maintained in all conventional scenarios of …

In quantum communication networks, wires represent well-defined trajectories along which
quantum systems are transmitted. In spite of this, trajectories can be used as a quantum …

Entanglement underpins a variety of quantum-enhanced communication, sensing, and
computing capabilities. Entanglement-assisted communication (EACOMM) leverages …

Quantum networks entangle remote nodes by distributing quantum states, which inevitably
suffer from decoherence while traversing quantum channels. Pertinent decoherence …

We present a new optical scheme enabling the implementation of highly stable and
configurable non-Markovian dynamics. Here one photon qubit can circulate in a multipass …

Many applications of the emerging quantum technologies, such as quantum teleportation
and quantum key distribution, require singlets, maximally entangled states of two quantum …

A quantum channel describes the general evolution of quantum systems, which is therefore
a critical issue for quantum simulation and a fundamental element of quantum information …

We represent an optical scheme using cross-Kerr nonlinearities (XKNLs) and quantum dot
(QD) within a single-sided optical cavity (QD-cavity system) to generate three-photon …

Correlations of fluctuations are essential to understanding many-body systems and key
information for advancing quantum technologies. To fully describe the dynamics of a …

In quantum optics, squeezing corresponds to the process in which fluctuations of a
quadrature operator are reduced below the shot noise limit. In turn, nonlinear squeezing can …
