Jülich's JUPITER used to simulate a record-scale quantum processor

Forschungszentrum Jülich ran a very large, detailed quantum processor simulation on the JUPITER supercomputer, per a headline-level report.

Forschungszentrum Jülich has used its JUPITER supercomputer to run what is described as the largest detailed simulation of a quantum processor to date. That is the extent of what we can confirm: the source was unreachable, so we have no figures on qubit counts, run time, or method.

The reason it matters is practical. Simulating quantum processors on classical machines lets researchers check and design quantum hardware before building it, which can shorten the path to quantum computers useful for science. Knowledge gets cheaper to produce when tools are tested in software first.

The source is brief on our end and the detail sits with them, so read the original AZoQuantum report for specifics and caveats.
