Intro to macros
It is possible to use python functions inside QUA programs. This technique where one programming language is used to write another is called metaprogramming and is a great way to write more powerful and readable QUA code.
In experiments where preparation and processing stages are needed, for example in quantum-dots and cold-atom experiments, separating those into macros are recommended. Such steps can be parameterized as demonstrated in this example file.
The program defined in
intro-to-macros.py showcase basic usage of macros.
A declaration of variables is first done in a macro. In this case, the variables must
be explicitly returned to the main program for them to be in its scope.
This program also returns an array of output streams, with default size =1.
The program then demonstrates how QUA statements can be initiated with a macro and parameterized such that reusable components can be set up.
