Microsoft Quantum Development Kit Samples
Role in this project:Backend Developer
Backend DeveloperContributions:275 reviews, 183 commits, 261 PRs in 4 years 7 months
Contributions summary:Cassandra primarily contributed to the development of the `microsoft/quantum` repository by fixing typos and implementing new functionality. They fixed a typo in a code file within the SimpleAlgorithms.qs samples. They added the `Compose` function and improved the unit testing functionality related to combinators in the project. Furthermore, they modified the ReversibleLogicSynthesis to include RLS.csproj into main solution, improved docs and inlined BindA and implemented additional test case, all while working within the context of quantum computing and quantum development samples.
