qpdbasis_from_instruction(gate, /)

Generate a QPDBasis object, given a supported operation.

All two-qubit gates which implement the to_matrix() method are supported. This should include the vast majority of gates with no unbound parameters, but there are some special cases (see, e.g., qiskit issue #10396).

The Move operation, which can be used to specify a wire cut, is also supported.

Return type:

QPDBasis

Returns:

The newly-instantiated QPDBasis object

Raises:

• ValueError – Instruction not supported.

• ValueError – Cannot decompose instruction with unbound parameters.

• ValueError – to_matrix conversion of two-qubit gate failed.
