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.…
