- 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.

- Co₃(dpa)₄Cl₂ consists of three linearly arranged cobalt ions and can change its spin state as a spin-crossover material.
- Magnetic measurements and pulsed EPR spectroscopy showed slow magnetic relaxation and sufficiently long spin lifetimes.
- The electron spin is delocalized across all three cobalt ions; clear Rabi oscillations also demonstrated coherent manipulation.
- The results experimentally showed for the first time that a metal-bonded molecule can function as a spin qubit, providing new design strategies.
