Expr variables order #146

Closed boschmitt closed 3 years ago

boschmitt commented 3 years ago

Description

Allow users to define variable order when parsing expressions for oracles. For example:

ExpressionParser("((A & C) | (B & D)) & ~(C & D)", var_order=["A", "B", "C", "D"])

Variables A, B, C, and D will be placed on qubits 0, 1, 2, and 3, respectively. If this was called without an order:

ExpressionParser("((A & C) | (B & D)) & ~(C & D)")

Then variables will be placed on qubits in order of appearance. That is, A, B, C, and D will be placed on qubits 0, 2, 1, and 3, respectively.

Suggested changelog entry:

Specify variable order for expressions parser
