We discuss our experience in enabling user-level multi-threading in QCOR as well as challenges that need to be addressed for programming future quantum-classical systems. Specifically, we discuss our design and implementation of introducing C++-based parallel constructs to enable 1) parallel execution of a quantum kernel with std::thread and 2) asynchronous execution with std::async. To do so, we provide a detailed overview of the ","authors_text":"Akihiro Hayashi, Alexander McCaskey, Austin Adams, Eugene Dumitrescu, Jeffrey Young, Thomas M.
