腔中超导量子比特的全连接网络

Fully-connected network of superconducting qubits in a cavity

D. I. Tsomokos, S. Ashhab, F. Nori

摘要:

考虑一个完全连接的量子位网络,其中每个量子位与每个其他量子位相互作用。当量子比特之间的相互作用是均匀的时,系统是有限Lipkin-Meshkov-Glick模型的特殊情况。我们提出了一个自然的实现这个模型使用超导量子比特在国家的最先进的电路QED。研究了体系的基态、低能谱和动力学演化。我们发现,在实际条件下,可以产生Greenberger-Horne-Zeilinger和W型的高纠缠态。我们还评论了无序对系统的影响,并讨论了用超导量子比特网络模拟复杂量子系统的可能性,如Sherrington-Kirkpatrick自旋玻璃。

英文摘要:

A fully-connected qubit network is considered, where every qubit interacts with every other one. When the interactions between the qubits are homogeneous, the system is a special case of the finite Lipkin-Meshkov-Glick model. We propose a natural implementation of this model using superconducting qubits in state-of-the-art circuit QED. The ground state, the low-lying energy spectrum and the dynamical evolution are investigated. We find that, under realistic conditions, highly entangled states of Greenberger-Horne-Zeilinger and W types can be generated. We also comment on the influence of disorder on the system and discuss the possibility of simulating complex quantum systems, such as Sherrington-Kirkpatrick spin glasses, with superconducting qubit networks.
