Limitations on Quantum Key Repeaters
A major application of quantum communication is the distribution of entangled particles for use in quantum key distribution. Owing to noise in the communication line, quantum key distribution is, in practice, limited to a distance of a few hundred kilometres, and can only be extended to longer distances by use of a quantum repeater, a device that performs entanglement distillation and quantum t...
متن کاملAll-photonic quantum repeaters
Quantum communication holds promise for unconditionally secure transmission of secret messages and faithful transfer of unknown quantum states. Photons appear to be the medium of choice for quantum communication. Owing to photon losses, robust quantum communication over long lossy channels requires quantum repeaters. It is widely believed that a necessary and highly demanding requirement for qu...
متن کاملLimitations on Quantum Control
Among a wealth of applications are those to Quantum Computing, where it is clearly essential to be able to start off a quantum procedure with a given initial state, and to problems involving the population levels in atomic systems, such as the laser cooling of atomic or molecular systems. The mathematical tools necessary for the theoretical investigation of these control problems are diverse, i...
متن کاملRepeaters for Continuous Variable Quantum Communication
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 be...
