NVIDIA’s Record simulation of a 104-qubit fault-tolerant quantum computer
NVIDIA researchers simulated a 104-qubit fault-tolerant quantum processor on JUPITER, the European supercomputer at the Jülich Supercomputing Centre. The run is the largest full simulation of a fault-tolerant quantum computer reported so far. The work also supports a resource-reduction approach that uses roughly 90% fewer physical qubits than earlier methods.

This could let quantum hardware teams use large-scale classical simulation to compare fault-tolerant architectures and error-correction codes before building hardware, accelerating the path to early logical qubits.
The simulation demonstrates that high-performance computing can model full fault-tolerant operations at a scale relevant to near-term logical processors, and the reduced-overhead technique implies more configurations can be explored within practical compute budgets. If hardware-specific noise models can be incorporated, the same tools could become a design-filtering step for chip developers.
