Construction of Cesium nutral atom array quantum computing system
POSTER
Abstract
Neutral-atom-based single-atom arrays offer several advantages for quantum computing, including scalability, precise control, and reconfigurability using optical tweezers. Leveraging these advantages, we employ cesium atoms to form a magneto-optical trap and use optical tweezers to prepare a single-atom array.
In basic single-atom characterization measurements, we achieve an average loading probability of approximately 57.66%, an atom lifetime of 3.68 s, and a temperature of 15.02 μK. For trap characterization, the measured trap depth is 0.573 mK, and the trap frequency is 59.62 kHz.
We further perform single-qubit Rabi oscillation experiments using stimulated Raman transitions. The coherence time T2∗ is characterized via Ramsey interference measurements. In the next stage, we plan to extend this platform to single-qubit gate operations and implement two-qubit CZ gates.
