What we do
We trap individual atoms with laser light, arrange them one by one, and use their interactions to recreate quantum systems that are too complex to compute — and to build sensors that measure electric fields with atomic precision.
Atomic Manipulation
Developing precision optical tweezers and single-atom arrays to architect quantum matter at the smallest scales.
Atom-Based Sensing
Engineering next-generation electric field sensors and vapor glass cells for high-sensitivity signal detection.
Progress
Building a neutral-atom quantum platform
Quantum simulation
2 of 7 milestones achieved
