Infleqtion, Honeywell and UCSB Develop Integrated Optical Cavity to Shrink Quantum Sensors to Handheld Size

Infleqtion, in collaboration with Honeywell Aerospace and UC Santa Barbara, has developed an integrated optical cavity that helps shrink quantum sensors down to handheld size. The University of California, Santa Barbara's (UCSB’s) Office of Technology & Industry Alliances facilitated the collaboration. Infleqtion’s engineering team and UCSB’s OCAQπ Group co-designed the prototype, then built it at the Honeywell Aerospace foundry using Honeywell Aerospace’s state-of-the-art silicon nitride photonic integration processes. The prototype is fabricated on a silicon nitride chip, and it reduces the space needed to keep lasers stable inside quantum systems. It is built using a manufacturing process common in...
