NVIDIA has run a 104-qubit simulation of a fault-tolerant quantum processor on JUPITER, Europe’s first exascale supercomputer at the Jülich Supercomputing Centre, using 8,192 GH200 GPUs. Announced ahead of GTC Berlin, the run models magic state cultivation, a method of producing the non-Clifford states a fault-tolerant computer consumes during logical operations, under realistic hardware noise.
