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.

A look back at Q#'s third year, 2020

Emulation in Q#

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

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.

Inside the Quantum Katas, part 1

Mariia Mykhailova December 2, 2020 Dec 2, 2020 12/2/20

Learn about the internal structure of the Quantum Katas - our collection of self-paced programming exercises on quantum computing - and their most important component – the testing harnesses that provide the learner immediate feedback on their solutions.

Q# Advent Calendar 2020

It is October, and this means it's time for Hacktoberfest - an annual celebration of open source! Meet our newest maintainer and learn how to participate in the Quantum Hacktoberfest.

Introducing Quantum Intermediate Representation (QIR)

Alan Geller September 23, 2020 Sep 23, 2020 09/23/20

QIR is a new Microsoft-developed intermediate representation for quantum programs. This post describes QIR and provides pointers to the specification and source code.

Build your own Q# simulator – Part 3: A circuit-diagram builder with ⟨q|pic⟩

Mathias Soeken August 13, 2020 Aug 13, 2020 08/13/20

We implement a custom simulator that generates a quantum circuit diagram in the ⟨q|pic⟩ format from Q# program execution traces.

Build your own Q# simulator – Part 2: Advanced features for the reversible simulator

Mathias Soeken June 2, 2020 Jun 2, 2020 06/2/20

This post is the second in a series on how to write your own Q# simulators. In this part we describe advanced features to extend the reversible simulator from the first post in the series.
