We propose a two-step approach to realize the fast multiqubit controlled-phase gate of one qubit simultaneously controlling N qubits in the circuit QED system composed of gradiometer-type flux qubits coupled to a transmission line resonator.Beyond the rotating-wave approximation, we obtain an effective XX coupling of qubits under two different conditions.

近年来,热光(赝热光)关联成像作为一种新的成像技术引起了国内外学者的广泛关注.热光场可以看作是由大量振幅和相位随机变化的子光源合成形成的,其强度满足瑞丽分布.其中,不同子光源的振幅和相位是统计无关的,并且相位均匀分布在[0,2π].不满足以上条件的光源能否实现关联成像?在本文中,我们对光源进行主动相位调制,研究了不同于热光的光源在关联成像中表现出的性质和对关联成像质量的影响.
