利用超导量子干涉器件量子比特在QED腔中制备团簇态和W态

Preparation of cluster states and W states with superconducting- quantum-interference-device qubits in cavity QED

X. L. Zhang, K. L. Gao, M. Feng

摘要:

我们提出了利用超导量子干涉器件(SQUID)量子比特在腔中产生团簇态和W态的方案。我们的方案不需要辅助量子位,并且激发能级在整个方案中仅虚拟耦合,这可以大大降低实验挑战。我们在模型中考虑了腔的衰减,并分析了它对制备纠缠态的不利影响。

英文摘要:

We propose schemes to create cluster states and W states by many superconducting-quantum-interference-device (SQUID) qubits in cavities under the influence of the cavity decay. Our schemes do not require auxiliary qubits, and the excited levels are only virtually coupled throughout the scheme, which could much reduce the experimental challenge. We consider the cavity decay in our model and analytically demonstrate its detrimental influence on the prepared entangled states.
