Optimal architectures for long distance quantum communication
Despite the tremendous progress of quantum cryptography, efficient quantum communication over long distances (≥ 1000 km) remains an outstanding challenge due to fiber attenuation and operation errors accumulated over the entire communication distance. Quantum repeaters (QRs), as a promising approach, can overcome both photon loss and operation errors, and hence significantly speedup the communi...
متن کاملArchitectures for Long-Distance Quantum Communication
A quantum communication system that is capable of long-distance, highfidelity teleportation, and long-duration quantum storage is proposed. This system uses polarization-entangled photons and trapped-atom quantum memories and is compatible with transmission over standard telecommunication fiber. An extension of this architecture permits long-distance transmission and storage of Greenberger-Horn...

A system architecture for achieving long-distance, high-fidelity teleportation and long-duration quantum storage is proposed. It uses polarizationentangled photons and trapped-atom quantum memories and is compatible with transmission over standard telecommunication fibre. An extension of this architecture permits long-distance transmission and storage of Greenberger– Horne–Zeilinger states.
متن کاملOptomechanical transducers for long-distance quantum communication.
We describe a new scheme to interconvert stationary and photonic qubits which is based on indirect qubit-light interactions mediated by a mechanical resonator. This approach does not rely on the specific optical response of the qubit and thereby enables optical quantum interfaces for a wide range of solid state spin and charge based systems. We discuss the implementation of state transfer proto...
متن کاملLong-distance quantum communication with neutral atoms
In this thesis, we develop quantitative performance analyses for a variety of quantum communication/computation systems that have the common feature of employing neutral atoms for storage/processing and photons for qubit transmission. For most of these systems, there is a lack of a precise performance analysis to enable a comparison between different scenarios from a top-level system standpoint...
