cWe harness the exquisite control of ultracold atoms to advance quantum science and technologies

Programmable quantum information transfer

The exponential growth of computational power demands all-to-all connectivity between qubits. However, practical quantum hardware is constrained by finite-range interactions. To overcome these connectivity limitations, quantum information transport becomes essential. We aim to leverage native interactions to achieve high-fidelity, high-speed, and programmable quantum information transport, enabling scalable quantum information processing. 

Quantum optics and sensing

Rydberg atoms possess two categories of strong interactions: with external fields and with each other. We explore the role of atomic interactions in quantum sensing applications, aiming to mitigate their negative effects and find contexts where those interactions are beneficial.
