- IBM, IBM Q
- Google Cirq
- Microsoft Q#
It seems IBM Q and Cirq are reusing the Python to provide a framework while Q# is a brand new language. It makes sense IBM and Google use Python as base as it has a good math library. However, I doubt this choice is the best choice. Like the GPU, quantum is special hardware. Cuda is a like C language but it has its own features. For quantum computing, it has a totally different way to compute. Therefore, I think the best way to use a new language, maybe it is just a DSL. C++ can be used to write a functional program, but the best way is still to use a functional programming language.
Also, the examples from those three companies show a huge difference. Q# provides the best sample pack so far. It has a quantum foundation, matrix computation, and programming language. It will help me a lot to adopt this new stuff.
The setup and debugging is the last thought. I had tried to step away from Microsoft stack; however, the debugging and the setup needs more time I expected. I was spoiled by double click and just working.
Anyway, the current Q# shows good progress and the watch, star, and pull request number is bigger than other players. I will continue to focus on the quantum basics, like matrix and math part, anyway.
