United StatesIBM will link two chips into 1,040 qubits.

IBM has cut its planned chain from nine linked chips to two.

Each Nighthawk r3 chip targets 520 programmable qubits, and couplers joining chips reached up to 99.4% state-transfer fidelity.

Oliver Dial, IBM’s vice president of quantum systems, says IBM is still working out how many couplers error-corrected chips need.

Reaching 100 logical qubits needs five or more larger chips linked by the end of next year.
