PsiQuantum
| Vacuum (at rest) | Dense cryogenic cabinets (no dilution chandelier) |
|---|---|
| Vacuum (operation) | Photonic platform; superconducting single-photon detectors; runs >100x warmer than superconducting qubits |
| Power | Datacenter-rack-style cryo cabinets (~1000x the cooling power of the largest dilution fridge); Linde Engineering to build the largest cryogenic plant ever planned for a quantum computer |
| Voltage | Low-voltage cryo control electronics; not a high-voltage object |
| Product | Fault-tolerant photonic quantum computer (Omega platform, 1550 nm telecom photons on ultra-low-loss silicon nitride); in-house barium-titanate optical switches and high-temperature single-photon detectors |
| Application | Large-scale quantum computing (~1M qubits targeted by 2027) |
| Customer | Governments, large accounts, national security |
Why it matters
Assembles its systems in a former semiconductor fab in Milpitas (now "PsiFactory"), next to SLAC. Young, with no lab vacuum tradition. The Linde partnership will build the largest cryogenic plant ever planned for a quantum computer — central challenges are materials, cryogenics, vacuum integration. Ideal ground for UHV + materials + cryo expertise.
