Neutral-Atom Quantum Computing Laboratory

Located in Room B053, our laboratory focuses on quantum computing experiments using Rb-87 and Cs-133 neutral atoms.

In an ultrahigh vacuum environment, we cool atoms to the millikelvin regime and trap them as single-atom arrays using optical tweezers. Through precise manipulation of atomic internal states with lasers and microwaves, along with mobile optical tweezers and Rydberg excitation, we achieve high-fidelity quantum gate operations and qubit preparation. Our research aims to advance fault-tolerant quantum computing and ultimately realize universal quantum computation.

The lab consists of two main experimental platforms:

1. Rb-based quantum computing system (for technical development)

2. Rb-Cs hybrid system (for fault-tolerant computing research)

Core experimental infrastructure includes:

- Dual ultrahigh vacuum systems

- Precision laser preparation optics

Key equipment:

- Vacuum pump assemblies

- Laser systems: 780 nm, 813 nm, 795 nm, 420 nm, 1013 nm, 852 nm, 1064 nm

- Ultra-stable optical cavity

- Scientific qCMOS camera

- Spatial light modulator (SLM)

- Acousto-optic deflectors (AODs)
