Quantum developer tools for chemistry

Guen Prawiroatmodjo March 18, 2021 Mar 18, 2021 03/18/21

Quantum computers will be able to reveal the exact quantum nature of chemical systems exponentially faster than classical computers. In this post, we show how to use Microsoft's Q# libraries and developer tools to simulate a caffeine molecule using two quantum algorithms: Quantum Phase Estimation and Variational Quantum Eigensolver.
