QC Ware

QC Ware describes itself as a provider of enterprise software and services for quantum computing. Its website highlights two main offerings: Promethium, a computational chemistry platform for molecular simulation and AI on GPUs, and quantum services for applying quantum computing to optimization and other computational problems. The company also says it founded the Q2B event series in 2017.

The site lists addresses in Palo Alto, California, and Paris, France, and presents Promethium as software designed for current GPU-based workflows with a path toward future quantum computing. QC Ware’s team page names co-founder and CEO Matt Johnson, co-founder and COO KJ Sham, President and CFO John Hynes, and Vice President of Quantum Algorithms Alejandro Perdomo Ortiz among its leadership.

In October 2026 a QC Ware researcher co-authored a preprint with Los Alamos National Laboratory scientists that used sample-based quantum diagonalization on IBM Quantum hardware to model the iron oxides FeO and Fe₂O₂.
