Quantum computing realized in single atom array

Neutral atom-based single-atom arrays offer key advantages for quantum computing, including scalability and precise control. In this work, we use a magneto-optical trap to capture cesium atoms and employ optical tweezers to arrange them into a single-atom array. We characterize the fundamental properties of our cesium atom array, including loading rate, atom lifetime, atom temperature, trap depth, and trap frequency, which are crucial for quantum gate operations in atom-based arrays. With precise individual-atom control and measurement capabilities, this system enables essential quantum computing operations, such as single-qubit and two-qubit gate implementations.
