Running QAOA on X8?

Photonic Software Strawberry Fields

Hey together!

i wanted to ask if it is possible to run QAOA on the X8 oder any other chip?

Thanks for your help!

Best Regards

Hey @PetMai and welcome to the forum!

QAOA requires the implementation of a Hamiltonian evolution, and it is not immediately clear (although not impossible?) to match this formalism to the setup of a GBS device - especially if it is a restricted architecture like the X8. Do you have something in mind, or are you just asking in general?

Checkout the apps layer for combinatorial optimisation problems and how to encode them into GBS!

Thank you very much for your answer!
I just want to know in general if it is possible because i read something about QAOA and the MaxCut-Problem on Pennylane, so i was wondering, if it would run on a quanten computer from Xanadu.
According to your answer it would not be possible, right?

Ah, I wonder if you are referring to this demo? If so, then this is unfortunately a qubit-based implementation, while the X8 is a special-purpose continuous-variable architecture.

But hopefully a future generation of chips will be able to do QAOA :slight_smile:

Yes, I did indeed mean this demo.
Alright, thanks for the clarification :slight_smile:
