光子与物质量子比特多体纠缠的制备

Preparing multi-partite entanglement of photons and matter qubits

Pieter Kok, Sean D. Barrett, Timothy P. Spiller

摘要:

我们展示了如何在量子比特之间产生事件准备的多体纠缠,这些量子比特可以被编码在光子或物质系统上。纠缠态物质系统,也可以作为单光子源,可以使用量子ph/0408040中提出的纠缠操作产生。我们展示了如何用光子量子比特纠缠这样的源,光子量子比特可以被编码在双轨、偏振或时间仓自由度中。随后,我们展示了如何投影测量的物质量子比特可以用来创建纠缠态的光子单独。物质量子比特的状态由生成的光子继承。由于纠缠操作可以用来生成用于量子计算的物质量子比特的团簇态,因此我们的过程使我们能够创建任何(纠缠)光子量子态,其可以被写入为量子计算机的结果。

英文摘要:

We show how to make event-ready multi-partite entanglement between qubits which may be encoded on photons or matter systems. Entangled states of matter systems, which can also act as single photon sources, can be generated using the entangling operation presented in quant-ph/0408040. We show how to entangle such sources with photon qubits, which may be encoded in the dual rail, polarization or time-bin degrees of freedom. We subsequently demonstrate how projective measurements of the matter qubits can be used to create entangled states of the photons alone. The state of the matter qubits is inherited by the generated photons. Since the entangling operation can be used to generate cluster states of matter qubits for quantum computing, our procedure enables us to create any (entangled) photonic quantum state that can be written as the outcome of a quantum computer.
