About QSimulate
QSimulate is a Cambridge-based quantum molecular simulation company founded in 2018 by Garnet Chan and Toru Shiozaki that develops cloud-based quantum chemical simulation tools for pharmaceutical, materials, and chemical companies. In August 2025, QSimulate partnered with Mitsui & Co. and Quantinuum to launch QIDO (Quantum-Integrated Discovery Orchestrator), a quantum-enabled chemistry platform that integrates QSimulate’s QSP Reaction software with Quantinuum’s InQuanto platform to enable high-precision chemical simulations. The company’s QSP platform enables customers to perform quantum chemical simulations modeling thousands of atoms with state-of-the-art quantum chemistry methods, enabling first-of-a-kind quantum simulations of ligand-protein interactions throughout the computational drug discovery pipeline. QSimulate has raised $11.34 million in total funding including a $2.5 million Series A round in 2023, with strategic partnerships including Japan Tobacco for small molecule drug discovery acceleration.
2025 Developments: The company continues to enhance its quantum software platform and developer tools in 2025. Focus remains on improving algorithm efficiency and expanding use case applications. Active engagement with the quantum developer community drives product evolution.
