Startup PsiQuantum has a rough vision of what its one-million-qubit quantum computer could look like.
“It’s going to look like a big concrete building with a whole bunch of modules,” Pete Shadbolt, chief scientific officer, told The Register.
“Inside those modules, a bunch of silicon chips, half photonic, half electronic, and the whole thing is wired together with the same optical fiber that you find today.”
PsiQuantum is thus betting that silicon photonics will play a central role in its data-center-sized quantum computer.
“When you think of quantum computing, you think of milli-kelvin temperatures, atoms flying around in space, atomic-scale fabrication, mad materials, science-fiction stuff. We need to repurpose something that’s already manufacturable,” Shadbolt said.
