The approach is designed for several technologies but explicitly excludes Microsoft’s own planned hardware.

Microsoft estimates that physical qubits with roughly one error per 1,000 could yield logical qubits with one per million.

The approach has so far relied on mathematical proofs and simulations; it has not been demonstrated on actual quantum hardware.

Atom Computing and Microsoft are building a first-generation machine with 1,200 physical qubits; its successor is planned to exceed 10,000.

This first generation that we are building together between Atom Computing and Microsoft will include state-of-the-art quantum capabilities, will have 1,200 physical qubits. And then the next upgrade of that machine will have upwards of 10,000. And so you’re looking at then being able to go to upwards of a hundred logical qubits with deeper and more reliable computation available.
