Enhance the Pulse-Level Simulation

[Hanrui-Wang]

We want to continue working to build up our pulse-level simulation. You can reference an example from QuTip and see our current implementation in pulse.

@Hanrui-Wang I want to defines the individual waveforms (pi pulse, up ramp, down ramp) and then concatenates them using tq.pulse.concat() to create a composite waveform
since this is not supported on torch quantum I dont know how to move forward with this

[AbdullahKazi500]

Hi @Hanrui-Wang instead of composite wave-forms I have added a different demo please review my PR

[Packman2002]

@Hanrui-Wang I would like to implement the quantum annealing algorithm using pulse-simulation and add it to the torch-quantum repo. I did not find any support for this, please let me know if you think this is possible and how to proceed?

I'd love to try implementing Monte Carlo sampling of quantum trajectories based on qutip.mcsolve - the very minimal example.
