Hi everyone,
I was wondering If there is any way of constructing an MPO from several two site gates where all gates are acting on different sites??

Do you mean an MPO that is a sum of gates, or a product of gates?

If the MPO is a sum of gates, you can use AutoMPO to easily create an MPO (as long as you write your gates in terms of products of local operators):


If you mean a product of gates, there is a formula here that shows how to do it for a particular gate structure:


The code would need to be adapted for other gate structures.

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.
