Quantum teleportation over the Swisscom telecommunication network

Quantum teleportation over the Swisscom telecommunication network

We present a quantum teleportation experiment in the quantum relay configuration using the installed telecommunication network of Swisscom. In this experiment, the Bell-state measurement occurs well after the entanglement has been distributed, at a point where the photon upon which data are teleported is already far away, and the entangled qubits are photons created from a different crystal and...

Small Scale Quantum Network Communications via Multi-step Quantum Teleportation

Motivated by multi-step quantum teleportation of single-qubit states and two-qubit states with entanglement swapping, we present a small scale quantum network communication scheme based on entanglement of Bell states. In this scheme, it contains certain number of singlequbit quantum source nodes that teleport unknown quantum states to other nodes in the network in the multiteleport fashion wher...

Opportunistic quantum network coding based on quantum teleportation

Quantum teleportation.

For continuous variable systems, some protocols for entanglement swapping, establishing entanglement between distant stations through teleportation, testing the efficiency of teleportation with the aid of a third party, and combining teleportation with cloning have been proposed. But no protocol for the explicit teleportation of an entangled continuous variable state exists in the literature, a...

Quantum Teleportation

Teleportation the transmission and reconstruction of objects over arbitrary distances is a spectacular process, which actually has been invented by science fiction authors some decades ago. Unbelievable as it seems in 1993 a theoretical scheme has been found by Charles Bennett et al. that predicts the existence of teleportation in reality at least for quantum systems. This scheme exploits some ...
