Briefings

PsiQuantum demonstrated an 8x8 optical circuit switching device using its silicon photonics platform, achieving 1.2 dB insertion loss, 40 dB crosstalk, and under 3 ms reconfiguration time without amplification. The company shared samples with prospective customers and plans commercial products for AI data centers while continuing quantum research. This marks the first public OCS demonstration for AI infrastructure, leveraging a decade of development for utility-scale quantum computing.

Key points

• PsiQuantum demonstrated an 8x8 optical circuit switching device using its silicon photonics platform, achieving 1.2 dB insertion loss, 40 dB crosstalk, and under 3 ms reconfiguration time without amplification.
• The company shared samples with prospective customers and plans commercial products for AI data centers while continuing quantum research.

Context

PsiQuantum is advancing optical switching technology to support AI infrastructure scaling, which demands efficient data connectivity. The company previously developed this platform for utility-scale quantum computing, now applying it to AI challenges. This announcement follows September 2026 documentation with the U.S. Department of Commerce to accelerate domestic manufacturing of critical components.

Limitations

Evidence is limited to a single press release from October 2026. Performance targets were exceeded but no specific customer contracts or commercial launch dates are confirmed. Future product announcements remain unconfirmed.
