PsiQuantum is building the first useful quantum computer.
A different kind of quantum computing company
At PsiQuantum our singular focus is on building the world’s first useful general purpose quantum computer. That end goal set us on a different path, with a different underlying technology — silicon photonic qubits produced in a conventional semiconductor fab.
Photonics is the only way to deliver
1,000,000qubits
A useful quantum computer requires at least a million qubits.
Our quantum computer will be built using the same industrial tools that produce your laptop.
Error correction is at the centre of everything we do. It is the only known way to ensure that such a complex device can function reliably.
Thirty years ago photonic quantum computing was believed impossible. Twenty years ago, it was proved possible but dismissed as impractical. Today, after numerous architectural breakthroughs and advances in silicon photonics, PsiQuantum uniquely has a clear path to a useful quantum computer.
