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.

Emulation in Q#

December 4, 2020 Dec 4, 2020 12/4/20

Mathias Soeken

It can be helpful to implement Q# functions or operations directly in C# - either to access some API that is not directly accessible in Q# or to provide alternative implementations based on the context in which the Q# program is executed. This blog post describes techniques to programmatically replace a Q# function by another one.
