The future development of quantum technologies relies on creating and manipulating
quantum systems of increasing complexity, with key applications in computation, simulation …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Quantum coherence is the key resource for quantum technology, with applications in
quantum optics, information processing, metrology, and cryptography. Yet, there is no …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

Entanglement is one of the most intriguing features of quantum mechanics. It describes non-
local correlations between quantum objects, and is at the heart of quantum information …

Distributed secure quantum machine learning (DSQML) enables a classical client with little
quantum technology to delegate a remote quantum machine learning to the quantum server …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

The transverse spatial effects observed in photon pairs produced by parametric down-
conversion provide a robust and fertile testing ground for studies of quantum mechanics …

We demonstrate the difference between local, single-particle dynamics and global dynamics
of entangled quantum systems coupled to independent environments. Using an all-optical …
