Quantum repeaters: From quantum networks to the quantum internet

Understand

A quantum internet is the holy grail of quantum information processing, enabling the deployment of a broad range of quantum technologies and protocols on a global scale.

• However, numerous challenges exist before the quantum internet can become a reality.
• Perhaps the most crucial of these is the realization of a quantum repeater, an essential component in the long-distance transmission of quantum information.
• As the analog of a classical repeater, extender, or booster, the quantum repeater works to overcome loss and noise in the quantum channels comprising a quantum network.
