Yao.jl is a fantastic project and I hope to keep following it in the future. Maybe we can build differential equation solver algorithms which utilize quantum algorithms :)
Actually, since we are planning to integrate QASM and eQASM (a new kind of assembly from Delft), if you can use Yao.jl to run a quantum algorithm for solving differential equations (there has been several already), you will be able to run it on some real hardware. Still working on more features, and we do need more feedback to help us make this better, please feel free to give us any comments in the issue :)
Cool, I'm not familiar with quantum at all but I'll start looking into it. It will definitely be something we add to DifferentialEquations.jl common interface next year. I'll see about getting a Google Summer of Code project on this.
