The impossibility of perfectly copying (or cloning) an unknown quantum state is one of the
basic rules governing the physics of quantum systems. The processes that perform the …

It is a fundamental consequence of the superposition principle for quantum states that there
must exist nonorthogonal states, that is, states that, although different, have a nonzero …

Quantum Machine Learning bridges the gap between abstract developments in quantum
computing and the applied research on machine learning. Paring down the complexity of the …

There are fundamental limits to the accuracy with which one can determine the state of a
quantum system. I give an overview of the main approaches to quantum state discrimination …

Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

We derive a generalized wave-particle duality relation for arbitrary multipath quantum
interference phenomena. Beyond the conventional notion of the wave nature of a quantum …

A photon in an arbitrary polarization state cannot be cloned perfectly 1, 2. But suppose that
at our disposal we have several copies of a photon in an unknown state. Is it possible to …

Signal amplification is ubiquitous in the control of physical systems, and the ultimate
performance limit of amplifiers is set by quantum physics. Increasing the amplitude of an …

In recent years, Quantum Computing witnessed massive improvements in terms of available
resources and algorithms development. The ability to harness quantum phenomena to solve …

Quantum computers will revolutionize the way telecommunications networks function.
Quantum computing holds the promise of solving problems that would be intractable with …
