量子剪刀:利用非局域单光子实现单模光学态的隐形传态

Quantum scissors: teleportation of single-mode optical states by means of a nonlocal single photon

S. A. Babichev, J. Ries, A. I. Lvovsky

摘要:

我们采用单光子与真空纠缠的量子态(|1,0>-|0,1>),通过Bennett协议传送光的单模量子态。隐形传态的相干态的Fock展开截断到前两项。我们分析的隐形传态合奏通过零差层析成像,并获得高达99%的低源状态振幅的quantiities。这项工作是Pegg,Phillips和Barnett(Phys. Rev. Lett.)提出的量子剪刀装置的实验实现。1604(1998))

英文摘要:

We employ the quantum state of a single photon entangled with the vacuum (|1,0>-|0,1>), generated by a photon incident upon a symmetric beam splitter, to teleport single-mode quantum states of light by means of the Bennett protocol. Teleportation of coherent states results in truncation of their Fock expansion to the first two terms. We analyze the teleported ensembles by means of homodyne tomography and obtain fidelities of up to 99 per cent for low source state amplitudes. This work is an experimental realization of the quantum scissors device proposed by Pegg, Phillips and Barnett (Phys. Rev. Lett. 81, 1604 (1998))
