I am trying to understand how it may be possible to maintain two particles in an entangled superposition.

Is this possible or has this already been done?

Your question could be interpreted several ways. No shortage of experiments demonstrating entanglement, if that is your question. If it is more about maintaining it for longer periods of time or over longer distances:

1 hour of entanglement

10 km separation (there has been much longer too, across the Canary Islands)

Dear Dr Chinese,

Thank you for the answer, I was trying to find out about entanglement maintained for long periods.

And its great to be here at Physics forum thanks.
