Repeaters for Continuous Variable Quantum Communication

Understand

Optical telecommunication is at the heart of today's internet and is currently enabled by the transmission of intense optical signals between remote locations.

• As we look to the future of telecommunication, quantum mechanics promise new ways to be able to transmit and process that information.
• Demonstrations of quantum key distribution and quantum teleportation using multi-photon states have been performed, but only over ranges limited to one hundred kilometers.
• To go beyond this, we need repeaters that are compatible with these quantum multi-photon continuous variables pulses.
