Added

  • Analysis pass to count operators.
  • Analysis pass to compute instructions' ALAP/ASAP layers.
  • Analysis pass to compute critical path.
  • Analysis pass to cut circuit.
  • Gate cancellation pass.
  • Pass to inverse (take adjoint) of a circuit.
  • Crude QASM 2.0 parser.
  • CX-Dihedral synthesis method.
  • Bridge operator.
  • Bridge decomposition pass.
  • Bridge mapping pass.
  • Sqrt(X) operator.
  • TFC parser.
  • Allow user to define var order for expressions.
  • Limited support for arm64, ppc64le and s390x.

Change

  • Rename depth pass to compute_depth.
  • Restructure of the code base.
  • Make Cbit, Qubit, and Instruction constructors public.
  • Invalidate ancilla reference on release.
  • Change Unitary operator global phase behavior.
  • Rename euler_decomp to one_qubit_decomp.

Deprecated

  • Circuit size() method. (Use num_instructions instead.)

Fixed:

  • Operator must clone the ConcreteOp class on copy.

1.0.0 - 2021-03-29
