Electronic structure problems in chemistry offer practical use cases around the hundred-qubit mark. This appears pro mising since current quantum processors have reached these sizes. However\ , mapping these use cases onto quantum computers yields deep circuits\, an d for for pre-fault-tolerant quantum processors\, the large number of meas urements to estimate molecular energies leads to prohibitive runtimes. As a result\, realistic chemistry is out of reach of current quantum computer s in isolation. A natural question is whether classical distributed comput ation can relieve quantum processors from parsing all but a core\, intrins ically quantum component of a chemistry workflow. In this seminar\, I will discuss the incorporation of quantum computations of chemistry in a quant um-centric supercomputing architecture\, using up to 6400 nodes of the sup ercomputer Fugaku to assist a Heron superconducting quantum processor. We simulate the N2 triple bond breaking in a correlation-consistent cc-pVDZ b asis set\, and the active-space electronic structure of [2Fe–2S] and [4F e–4S] clusters\, using 58\, 45 and 77 qubits respectively\, with quantum circuits of up to 10570 (3590 2-qubit) quantum gates.\n LOCATION:https://researchseminars.org/talk/TalentQ/5/ END:VEVENT END:VCALENDAR
