PsiQuantum samples an 8x8 optical switch for AI networks, reporting 1.2 dB loss
Co-founded by Jeremy O'Brien, PsiQuantum unveiled the demonstration switch on October 28th and reported typical insertion loss of 1.2 dB in its own lab tests.

Why it matters
AI clusters are limited by how fast GPUs can exchange data, and every optical hop that leaks light or converts signals costs power and reach. PsiQuantum's low-loss platform, built for fault-tolerant quantum computers, could give it an edge in optical circuit switching if the advantage survives the move from 8 ports to 64 and beyond. The launch also gives the quantum company a nearer-term market to court and a manufacturing supply chain to harden before its quantum machines arrive.
PsiQuantum co-founder Jeremy O'Brien built the business around the thesis that useful quantum computing would require semiconductor-scale manufacturing. PsiQuantum is applying the resulting low-loss photonics platform to optical switching for AI data centers.…
