GoKawiilPsiQuantum Unveils Optical Circuit Switch Based on Its Quantum Photonics Chips
PsiQuantum has revealed its first publicly disclosed Optical Circuit Switching device, an 8x8-radix demonstration built using the silicon photonics platform it originally developed for quantum computing. Lab testing showed 1.2 dB insertion loss, 40 dB crosstalk, and under 3 ms reconfiguration time without amplification, surpassing the company's initial targets. PsiQuantum is distributing samples to select prospective customers and plans to announce commercial products in coming months.
GoKawiil's interpretation of the reporting above, not reported fact.
The move suggests PsiQuantum is seeking to commercialize spillover technology from its quantum computing research to address networking bottlenecks in AI data centers, potentially diversifying its business beyond quantum hardware. The company frames quantum and AI infrastructure as mutually reinforcing, implying that revenue or technical progress from optical switching could help fund or accelerate its core quantum ambitions. Whether this translates into real market traction depends on performance against established optical switching competitors once commercial products ship.
- PsiQuantum's OCS demonstration achieved 1.2 dB insertion loss, 40 dB crosstalk, and sub-3ms reconfiguration without amplification.
- The switch reuses silicon photonics technology built for fault-tolerant quantum computing, repurposed for AI data center networking.
- Samples are being shared with select customers now, with commercial products expected in coming months.
