- The proposed machine does not yet exist and would route photons through optical switches and beam splitters.
- PsiQuantum raised $1 billion in 2025 and connected three cabinets with 250 chips each at its Milpitas facility.
- The company expects its Australian facility to be operational by the end of 2027, but does not thereby promise that a large computer will be complete.
- PsiQuantum has been assessed by the US research agency DARPA since 2023 and entered the program’s third stage in 2025.
Whenever we have more power to calculate and simulate and understand things, we build incredible machines that come from it.— Terry Rudolph, cofounder of PsiQuantum, in an interview about the implications of increased calculation and simulation power for quantum computing.
