Quantum Communication

Quantum information and computation - Charles H. Bennett , David P. DiVincenzo

Quantum Key Distribution

Factors preventing wide adoption of quantum key distribution outside high security areas include the cost of equipment, and the lack of a demonstrated threat to existing key exchange protocols. However, with optic fibre networks already present in many countries the infrastructure is in place for a more widespread use.

How to improve cybersecurity through quantum technology ?

Quantum Internet

A quantum internet supports numerous applications, enabled by quantum entanglement. In general, quantum entanglement is well suited for tasks that require coordination, synchronization or privacy.

Examples of such applications include quantum key distribution,[3][4] clock synchronization,[5] protocols for distributed system problems such as leader election or byzantine agreement[citation needed], extending the baseline of telescopes,[6] as well as position verification, secure identification and two-party cryptography in the noisy-storage model. A quantum internet also enables secure access to a quantum computer[7] in the cloud.

Milestone Experiment Proves Quantum Communication Really Is Faster

In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
