Architectures for Long-Distance Quantum Communication
نویسنده
چکیده
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-Horne-Zeilinger states.

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 کاملCircuit Design for A Measurement-Based Quantum Carry-Lookahead Adder
We present the design and evaluation of a quantum carry-lookahead adder (QCLA) using measurement-based quantum computation (MBQC), called MBQCLA. QCLA was originally designed for an abstract, concurrent architecture supporting long-distance communication, but most realistic architectures heavily constrain communication distances. The quantum carry-lookahead adder is faster than a quantum ripple...
متن کاملRobust long-distance quantum communication with atomic ensembles and linear optics
Quantum communication deals with absolutely secure transfer of classical messages by means of quantum cryptography or faithful transfer of unknown quantum states by means of quantum teleportation between distant sites. The essential element for quantum communication is to create remote entangled pairs of high fidelity. The main difficulty to create such a distant entangled pair is that both pho...
متن کاملUltranarrow-band photon-pair source compatible with solid state quantum memories and telecommunication networks.
We report on a source of ultranarrow-band photon pairs generated by widely nondegenerate cavity-enhanced spontaneous down-conversion. The source is designed to be compatible with Pr(3+) solid state quantum memories and telecommunication optical fibers, with signal and idler photons close to 606 nm and 1436 nm, respectively. Both photons have a spectral bandwidth around 2 MHz, matching the bandw...
