Since physicists have been dealing with the theoretical description of molecules, the solving of quantum mechanical equations has been a major obstacle. This is supposed to be a thing of the past with the release of an open source based system. Google has introduced such a system to the public with worldwide cooperation partners.
This application will enable researchers and companies to solve problems in different areas of the development of new substances and materials. The method enables simulations and modeling of compounds, for example in materials science or drug development, and to evaluate their properties.
The alpha-release of this platform was developed in cooperation with ETH Zurich, the Lawrence Berkeley National Laboratory, the University of Michigan, Harvard and Oxford Universities, NASA and many others.
OpenFermion encodes quantum mechanical problems in algorithms that are understandable for quantum computers. The platform uses quantum algorithms based on classical quantum chemistry packages developed and used by researchers worldwide.

Plastic gets a do-over: Breakthrough discovery recycles plastic from the inside out
Light yet sturdy, plastic is great - until you no longer need it. Because plastics contain various additives, like dyes, fillers, or flame retardants, very few plastics can be recycled without loss in performance or aesthetics. Even the most recyclable plastic, PET - or poly(ethylene tereph ... more
