- 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.— Krysta Svore of Microsoft's Azure Quantum team, discussing the Atom Computing collaboration

- Microsoft announced a topological quantum computer in February 2025, but a Nature peer-review note said the study had not definitively demonstrated Majorana zero modes.
- Google unveiled its 105-qubit Willow chip in December 2024, after which Mark Zuckerberg voiced doubts and quantum-computing stocks fell.
- Amazon announced the nine-qubit Ocelot chip at the end of February 2025, using a superconducting resonator and photon-controlled, error-tolerant cat qubits.
- No clear winner has emerged among the competing technical approaches, and scaling them to about one million qubits remains uncertain.
The Majorana 1 processor offers a clear path to fit a million qubits on a single chip that can fit in the palm of one’s hand.— Microsoft (from a press release about the Majorana-1 processor)
