IBM connected two 120-qubit Nighthawk processors with four cable links and moved quantum states between them at 99% average fidelity, according to a preprint not yet peer reviewed.
A superconducting chip from startup Great Sky processed tokamak data at one million samples per second in tests led by Brookhaven National Laboratory. No paper has been published yet.
Quantinuum says color-code error correction on its Helios trapped-ion computer reached logical error rates near five per million, 10 times lower than its September record.
Ai2's HiRO-ACEv2 generates global 3 km rain, wind and pressure data, including hurricanes, for roughly 300 times less than the physics model it imitates, a preprint reports.
A Nature paper from Ai2 and university partners shows existing language models can be converted to read raw bytes using less than 1% of a typical pretraining budget.
