Fourth production release. This is a major update introducing many new features:

  • Added (alpha version) of a "cloud library" for sharing / storing molecular data files.
  • Added routines for generating special FermionOperators such as Sz, S^2, S^+, etc.
  • Added SymbolicOperator as parent class from which FermionOperator/QubitOperator inherit.
  • Added flexible method of initializing classes derived from SymbolicOperators from strings.
  • Fixed some numerical instabilities in sparse operator routines.
  • Fixed some minor bugs with the saving and loading of FermionOperator/QubitOperator.
  • Added some preliminary routines for generating quantum phase estimation circuits.
  • Added substantial infrastructure for generalized fermion transforms based on arXiv:1712.07067.
  • Added non-linear encoders for transforming fermions with reduced spatial complexity.
  • Changed conventions for how fermion modes are ordered in terms of the spin index.
  • Added routines to transform functions for reordering fermion modes prior to transform.
  • New demos for Given routine procedures and generalized fermion encodings.
