Briefings

Infleqtion, Honeywell Aerospace, and UC Santa Barbara collaborated to fabricate a chip-scale optical cavity prototype using silicon nitride photonic processes. Led by Professor Daniel J. Blumenthal at UCSB, the project aims to miniaturize quantum sensors for precision navigation and atomic timing. The prototype was built at Honeywell's foundry, utilizing manufacturing techniques common in the semiconductor industry to enable commercial production. The collaboration was facilitated by UCSB's Office of Technology & Industry Alliances (TIA), which managed IP and supported the development of SiNoptiq, a startup acquired by Infleqtion in 2024.

Key points

• The chip-scale optical cavity prototype was fabricated on a silicon nitride chip using photonic manufacturing processes developed at Honeywell Aerospace's foundry.
• The collaboration between Infleqtion, UCSB, and Honeywell Aerospace was facilitated by UCSB's Office of Technology & Industry Alliances (TIA), which managed intellectual property and supported the development of SiNoptiq, a startup acquired by Infleqtion in 2024.

Context and limitations

This briefing covers the development of a chip-scale optical cavity prototype. It does not include data on the specific performance metrics of the cavity, the timeline for commercial production, or the cost of manufacturing the prototype.
