Abstract
Recently, quantum information processing (QIP) on acoustics wave resonators (AWRs) has attracted much attention as the quality factor of AWR has been increased to 1011, which means the time of phonons stored in the AWR can reach the order of seconds. To achieve the large-scale QIP on AWRs, one should complete quantum entangled operations on nonlocal AWRs. Different from previous work, we propose a one-step all-resonance scheme to generate Bell states on two nonlocal AWRs coupled to two nitrogen-vacancy center ensembles (linked by an AWR quantum bus) respectively. One-step all-resonance operation makes the scheme easier to be experimentally implemented.
