- 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.

Key FactsQuantum Computers: Promise Despite Fragile Qubits

- Quantum computers use qubits that can exist in superpositions and become entangled with one another, rather than classical bits.
- The most advanced quantum computers currently have hundreds of interconnected qubits and make an error roughly once in every thousand operations.
- Scientists hope for applications in molecular and materials simulations, complex optimization problems and analysis of encrypted data, but most remain years or decades away.
- The article says a quantum computer running Shor’s code-breaking algorithm might require millions of qubits operating error-free indefinitely, while today’s systems mainly serve research and testing purposes.
"It seems to me we're just on the threshold of quantum systems doing genuinely new simulations that we can't do classically," says Glancy. "It might inspire a revolution in physics. In my opinion that is a good reason to build a quantum computer."— Scott Glancy, a physicist at NIST, quoted in the NIST article Quantum Computing Explained
