自旋为1粒子的暗态绝热通道

Dark State Adiabatic Passage with spin-one particles

Andrew D. Greentree, Belita Koiller

摘要:

信息的绝热传输是与量子信息处理和分布有关的广泛调用的资源。通过自旋半链或团簇的绝热输运的研究在文献中是标准的,而在实践中,完全隔离的两能级量子系统的真正实现是无法实现的。我们在这里探索,理论上,自旋半链模型的扩展到更高的自旋。考虑到三个自旋一粒子的安排,我们表明,绝热运输,特别是一个概括的暗态绝热通道程序,是适用于自旋一系统。因此,我们证明了一个qutrit状态转移协议。我们讨论了可能的方式来实现这个协议,考虑量子点和氮空位的实现。

英文摘要:

Adiabatic transport of information is a widely invoked resource in connection with quantum information processing and distribution. The study of adiabatic transport via spin-half chains or clusters is standard in the literature, while in practice the true realisation of a completely isolated two-level quantum system is not achievable. We explore here, theoretically, the extension of spin-half chain models to higher spins. Considering arrangements of three spin-one particles, we show that adiabatic transport, specifically a generalisation of the Dark State Adiabatic Passage procedure, is applicable to spin-one systems. We thus demonstrate a qutrit state transfer protocol. We discuss possible ways to physically implement this protocol, considering quantum dot and nitrogen-vacancy implementations.
