The distribution of quantum states over long distances is limited by photon loss.
Straightforward amplification as in classical telecommunications is not an option in quantum …

Quantum communication (QC), namely, the faithful transmission of generic quantum states,
is a key ingredient of quantum information science. Here we demonstrate QC with …

Quantum networks build on entanglement and quantum measurement to achieve tasks that
are beyond the reach of classical systems. Using quantum effects, we can detect the …

Any physical process can be represented as a quantum channel mapping an initial state to a
final state. Hence it can be characterized from the point of view of communication theory, ie …
