For systems consisting of distinguishable particles, there exists an agreed upon notion of
entanglement which is fundamentally based on the possibility of addressing individually …

Entanglement is nowadays considered as a key quantity for the understanding of
correlations, transport properties and phase transitions in composite quantum systems, and …

Identical particles and entanglement are both fundamental components of quantum
mechanics. However, when identical particles are condensed in a single spatial mode, the …

We introduce the concept of a quantum walk with two particles and study it for the case of a
discrete time walk on a line. A quantum walk with more than one particle may contain …

We study properties of entangled systems in the (mainly non-relativistic) second
quantization formalism. This is then applied to interacting and non-interacting bosons and …

Quantum coherence plays a fundamental and operational role in different areas of physics.
A resource theory has been developed to characterize the coherence of distinguishable …

Abstract The Hong–Ou–Mandel (HOM) dip has played an important role in recent linear
optics experiments. It is crucial for quantum computing with photons and can be used to …

A complete treatment of open quantum systems made of identical particles has remained
elusive due to the intrinsic problem of these particles being individually unaddressable …

Quantum-mechanical entanglement is essential for certain forms of quantum
communication, and occurs as a consequence of some operations in quantum computation …

Quantum mechanics allows identical particles to lose their individuality completely and
become truly indistinguishable. This property of indistinguishability gives rise to exclusive …
