Stay up to date with the latest Boulder Opal release notes

Boulder Opal 18.2.0

May 16, 2022

What’s new

  • We've added simpler ways to create common operations of quantum mechanics:
    • The new operation number_operator creates the number operator in the Fock space.
    • The operation pauli_matrix now can also create the raising and lowering matrices.
  • We've added the operation ms_phases_multitone to calculate the phases produced by a Mølmer–Sørensen gate created with a multitone global beam.
  • We've added the unified graph operation hermitian_part for taking the Hermitian part of any of the data types used in our graphs (Tensors, PWCs, or STFs).
  • You can now pass any kind of SciPy sparse matrix format to graph operations that use sparse matrices, such as density_matrix_evolution_pwc.

What’s new

  • We've added new graph operations to create Pauli operators.

Boulder Opal 18.0.0

April 14, 2022

Breaking changes

  • We’ve removed support for Python 3.6.

What’s new

  • We’ve added support for Python 3.10.
  • We’ve added new graph operations to work with quantum harmonic oscillator-like systems. You can use them to easily create states and operators in Fock spaces.
  • The cut_off_frequency parameter in the sinc_convolution_kernel node is now deprecated and will be removed in the future. Please use cutoff_frequency instead.
