中性原子量子比特阵列的快速连续相干原子重载

atom reloading in a neutral- atom qubit array Yiyi Li1†, Yicheng Bao1†, Michael Peper1†, Chenyuan Li1,2, Jeff D. Thompson1* Neutral- atom quantum processors are a promising platform for scalable quantum computing. An obstacle to implementing deep quantum circuits is managing atom loss. Current approaches require at least an order of magnitude longer time than gate and measurement operations to replace lost atoms. In this work, we demonstrate fast, continuous atom reloading that leverages the metastable 171Yb qubit. A continuously loaded reservoir near the computation zone enables on- demand atom extraction with tweezers up to 500 times per second. New, stochastically filled qubit arrays can be initialized 30 times per second when including single- atom preparation, nondestructive imaging, and initialization. …
