- Loon connects each qubit to six others; its vertical links are unprecedented among superconducting quantum computers.
- Nighthawk connects each qubit to four others; IBM says it ran programs 30 percent more complex in preliminary tests.
- IBM’s approach could enable error-free computations without requiring the construction of millions of qubits.
- IBM plans a modular quantum computer for 2026 that stores and processes information, informed by testing of Loon and Nighthawk.
"You're in theory land, you cannot realise that." And [now] we're going to show that [to be] wrong.— Jay Gambetta, IBM — on critics who claimed IBM's approach was theoretical and unrealisable, and the aim to prove them wrong.

- Google’s Quantum AI Lab in Goleta announced a successful run of the Quantum Echoes algorithm on the superconducting Willow processor.
- The 105-qubit chip operates near absolute zero, uses error correction, and achieves single-qubit fidelities above 99.9 percent.
- The method could analyze molecular structures, support new drugs and materials, and generate training data for scientific AI.
- Quantum computing remains experimental; independent researchers view Google’s work as meaningful progress between theoretical physics and practical technology.

- 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
