About Q-Chem

Q-Chem, Inc. brings commercial, academic and government scientists worldwide in pharmaceuticals, materials science, biochemistry and other fields a comprehensive ab initio quantum chemistry program to solve computational problems faster, more accurately and less expensively than they could otherwise. Q-Chem also provides users with the highest level of technical support possible. The company was established in 1993.

Thousands of Q-Chem copies are being used around the world. About 55,000 licensed copies of Q-Chem have been sold up to date through Spartan alone. The citations of the two Q-Chem papers reached 300 per year in 2014, and is growing (as reported by ISI Web of Science). As part of the IBM World Community Grid, about 350,000 Q-Chem calculations are performed every day by the Harvard Clean Energy Project , which is powered by Q-Chem, free of charge.

QChem Research

Q-Chem is an open-teamware project. The source code is open to a large group of developers (currently more than 100 individuals in 9 countries), who can also check in their features to appear in the official releases as long as they do not violate the integrity of the code and are scientifically sound. To apply to become a developer, contact Dr. Zhengting Gan at zgan@q-chem.com. Successful applicants will be asked to sign a non-disclosure agreement pledging to respect intellectual property of other developers by protecting the code from unauthorized access.
