Quantum computing based on neutral atoms in a tweezer array is a promising platform. Our goal is to initially establish an analogue quantum simulator, with the long-term vision of evolving it into a quantum computing system. In this presentation, I will first introduce the state-of-the-art strontium system for the tweezer array. We have investigated the survival fraction of a single atom within the tweezers and characterized the optical tweezer array. By utilizing an array of multiple reservoirs, we have enhanced the loading rate of single atoms into the tweezer arrays, thereby conserving the power of our limited power Titanium-Sapphire (Ti-Sapphire) laser. Additionally, we have employed a generative neural network to expedite the creation of tweezers without the need for the traditional iterative processes.
Dr. Wenkai, a postdoctoral researcher under Professor Gyu-boong JO at HKUST (GZ) since 2022, completed his doctorate under Professor Jing Zhang at Shanxi University's Quantum Optics and Photonic Quantum Technology Key National Laboratory in 2021. His doctoral work involved developing an efficient magnetic transport system for 87Rb Bose-Einstein condensates (BEC) and exploring momentum lattice-based matter wave interference, two-dimensional quantum gases, and twisted optical lattices. His current research concentrates on quantum simulation and quantum computing with Rydberg arrays. The lab has successfully manipulated single atoms in optical tweezers and reconfigured one-dimensional arrays. We are currently dedicated to the intricate preparation of clock and Rydberg states.
