- A team led by Lieven Vandersypen moved qubits across silicon using conveyor-mode shuttling.
- Two electrons began in separate quantum dots, were brought together by moving electrical fields, and enabled a logic operation.
- In a second experiment, researchers entangled two electrons and transferred a third qubit’s state to another electron elsewhere on the chip.
- Researchers expect the architecture to play a key future role, but many challenges remain before everyday quantum computers.

- 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.
