基于自旋系统的量子信息存储和状态转移

Quantum information storage and state transfer based on spin systems

Z. Song, C. P. Sun

摘要:

将量子态存储的思想推广到描述量子信息通过相干数据总线的相干传输。在这个统一的框架下,我们全面回顾了我们最近的系统研究,探讨了利用量子自旋系统实现量子信息存储和状态转移的物理过程的可能性,量子自旋系统可以是各向同性反铁磁自旋梯系统或铁磁海森堡自旋链。我们的研究重点是固态系统中量子信息存储和传输的各种协议背后的物理机制和基本问题。

英文摘要:

The idea of quantum state storage is generalized to describe the coherent transfer of quantum information through a coherent data bus. In this universal framework, we comprehensively review our recent systematical investigations to explore the possibility of implementing the physical processes of quantum information storage and state transfer by using quantum spin systems, which may be an isotropic antiferromagnetic spin ladder system or a ferromagnetic Heisenberg spin chain. Our studies emphasize the physical mechanisms and the fundamental problems behind the various protocols for the storage and transfer of quantum information in solid state systems.
