- 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

- 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
