Quantum information is a rapidly advancing area of interdisciplinary research. It may lead to
real-world applications for communication and computation unavailable without the …

Quantum information theory is a branch of science at the frontier of physics, mathematics,
and information science, and offers a variety of solutions that are impossible using classical …

The counter-intuitive aspects of quantum physics have been for long illustrated by thought
experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now …

In recent years, there has been a rising interest in high‐dimensional quantum states and
their impact on quantum communication. Indeed, the availability of an enlarged Hilbert …

We investigate the “teleportation” of a quantum state using three-particle entanglement to
either one of two receivers in such a way that, generally, either one of the two, but only one …

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 …

Quantum computation and information is a new, rapidly develo** interdisciplinary field.
Therefore, it is not easy to understand its fundamental concepts and central results without …

A quantum telecloning process combining quantum teleportation and optimal quantum
cloning from one input to M outputs is presented. The scheme relies on the establishment of …
