论文摘要
在这里,我们报告了在超导电路中一对相关光子对两个非互动原子同时激发的首次观察。该过程的强耦合态度使三体相互作用的哈密顿量可以综合,这使三方Greenberger-Horne-Zeilinger-Zeilinger State在一个步骤中以高达0.95的忠诚度生成。我们进一步证明了通过连续测量是否发出第一个光子来抑制同时两种原子激发的量子ZENO效应。这项工作提供了一条新的途径,以综合杂项和连贯的纠缠控制多体相互作用。
Here we report the first observation of simultaneous excitation of two noninteracting atoms by a pair of time-frequency correlated photons in a superconducting circuit. The strong coupling regime of this process enables the synthesis of a three-body interaction Hamiltonian, which allows the generation of the tripartite Greenberger-Horne-Zeilinger state in a single step with a fidelity as high as 0.95. We further demonstrate the quantum Zeno effect of inhibiting the simultaneous two-atom excitation by continuously measuring whether the first photon is emitted. This work provides a new route in synthesizing many-body interaction Hamiltonian and coherent control of entanglement.
