- 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.
