Use dimension option in XIR program

[Mandrenkov]

Context:
The Jet-XIR interpreter does not currently support CV circuits with a Fock ladder cutoff greater than two. This is a consequence of the fact that the Jet-XIR interpreter always constructs Circuit instances with qudits of dimension two.

Description of the Change:

• A dimension attribute has been added to the Gate class.
• A pair of abstract FockGate and QubitGate classes now handle the validation of Gate dimensions.
• The cutoff parameter is now automatically inserted for CV gates by the Jet-XIR interpreter.
• The dimension option of an XIR program is now validated and used to construct Circuit instances.

Benefits:

• The Jet-XIR interpreter can handle CV circuits with a Fock ladder cutoff greater than two.
• There is no need to explicitly state the cutoff dimension of each CV gate in an XIR script.

Possible Drawbacks:
None.

Looks good! Much nicer to be able to use a script-level option to set the dimension rather than to have to add it as a gate argument. 🙂

That's right!
