integrate with qutip mesolve ? #48

Closed Papageno2 closed 1 year ago

Papageno2 commented 1 year ago

Hi, An impressive repository for GPU utilization!

I'm curious if this can seamlessly integrate with qutip. I see the paper tqix.pis: A toolbox for quantum dynamics simulation of spin ensembles in Dicke basis with a section name "Appendix A: An example code for employing a quantum circuit in qutip.pis", maybe qutip is a typo?

My goal is to perform dynamic simulations, specifically simulating the open Dicke mode in a driven-dissipation scenario. Could you provide guidance on how to achieve this?

thx.

Hello,

I appreciate your comment. There appears to be a typo with "qutip.pis." The correct term is "tqix.pis." For conducting dynamic simulations involving the open Dicke mode, you can utilize "qutip.piqs" from the Qutip library. For a detailed understanding of how we compute the dynamics of this Dicke model with modifications to "qutip.piqs," you can refer to Appendix B in this paper: https://journals.aps.org/pra/abstract/10.1103/PhysRevA.102.022602.

In our platform, "tqix," currently lacks the capability to perform such dynamic simulations. Presently, we employ Kraus operators for managing these dynamics, which are limited to full Hilbert-Space systems (2^N).

Best regards,
