Is it possible to force double precision with the "Dynamics" target ?

[SimonRicher]

Hi,

I am trying to create a cudaQ dynamic simulation and I am wondering if my evolve call is using double or single precision. Is there a way to force one or the other ? I have tried :
cudaq.set_target('dynamics',options="fp64")
but I still get SimulationPrecision.fp32 when verifying with :
target.get_precision()

Hi @SimonRicher,

The dynamics target in evolve uses double precision.
There is an oversight in the target definition (not explicitly declaring it); hence the reported value in target.get_precision() is incorrect (the default value).

We'll post a fix for this.

Thanks for the quick answer !
