This PR includes:

  • A new simulation algorithm TTNxGate currently only supporting:
    • exact and approximate chi-bound simulation.
    • some basic TTN state querying functions (vdot, get_amplitude, get_statevector)
  • A new abstract class TNState that encapsulates both MPS and TTN.
  • Updated docs
  • Updated the MPI examples for the new API.
  • Updated the MPS Jupyter notebook for the new API.

TODO

  • Merge the three pending feature/ttn_* PRs into this one
  • Cleanup the bonds_from_q0_to_ancestor code and sanity checks after merging the above
  • Check the code again to look for weird artefacts created by merging the PRs
  • Run tests locally
  • Add stuff to changelog (under "Unreleased")
  • Check that the generated docs look good
  • Change the name of tnstate module to structured
  • Write a new Jupyter notebook for TTN

We agreed that the tasks that remain (see below) will be done on a separate PR.

  • Add stuff to changelog (under "Unreleased")
  • Check that the generated docs look good
  • Write a new Jupyter notebook for TTN
  • Add a NetworkX option for _get_qubit_partition to not depend on KaHypar installation
