Kind: research · Impact: medium

## In brief

- Qunova Computing reported that its HI-VQE algorithm reached chemical accuracy in an 80-qubit simulation of an iron-sulfur cluster.
- The simulation ran on an IBM quantum computer together with RIKEN's Fugaku supercomputer.
- The workflow's extrapolated ground-state energy estimate agreed with the classical benchmark within chemical accuracy.

## Why it matters

It is a reported hybrid quantum-classical result on a chemically relevant iron-sulfur system, a class of molecules that is hard to model classically. Readers should still treat it as a single company's report of a benchmark comparison.
