PsiQuantum says photonic device could ease the AI data center's weakest link
Company claims racks would behave as one, with data moving between GPUs at speed of light and almost no heat
PsiQuantum, a quantum computing company whose first breakthrough is in AI data centers, says it has developed a device that routes light signals without converting them to electricity, allowing separate server racks to behave as one at speed-of-light latency with almost no heat and negligible energy use.
