Best way to create equal amplitude states

+1 vote
asked by (150 points)

I need to create equal amplitude superposition (RK type) superpositions to use as initial states in dynamics.

I checked and the required bond-dimension is not onerous, so it should be possible to represent these using MPS

Claude suggested two methods that I knew of (brute force construction and imaginary time evolution approximation to the projector) and the third which seemed more elegant using

MPO(sites, "MaxEntangler")

seems like a neat trick but I never heard of MaxEntangler .. any quick thoughts?

thanks,vadim

Formatting Tips:
  • To format code, indent by four spaces
  • To format inline LaTeX, surround it by @@ on both sides
  • To format LaTeX on its own line, surround it by $$ above and below
  • For LaTeX, it may be necessary to backslash-escape underscore characters to obtain proper formatting. So for example writing \sum\_i to represent a sum over i.
