Lead story

IBM connected its first two cryogenic modules, the step that has to work before 2029

The two joined modules stand over eight feet tall, cool to 4 kelvin in under five days and settle below 15 millikelvin. Each carries twelve times the wiring space of IBM's existing quantum systems, which is the constraint that decides how many qubits fit in one machine.

14 Aug 2026 · 00:02:18A Quantum Computer Moves In Next DoorOracle and Quantinuum announced a multi-year partnership on 11 August to deploy Helios, the 98-qubit trapped-ion system, inside a US Oracle Cloud AI data centre, with an OCI quantum service to preview in the coming months.11 Aug 2026 · 00:02:14Pasqal put the optical bench on a chip. It held four atomsPasqal says it is the first to trap atoms on a quantum computer using light generated by a photonic chip rather than a bench of free-space optics. Four traps, four rubidium atoms, and an atom lifetime of about 27.5 seconds.
