Research direction

Read the MajoranaPropagator implementation and build_graph entry point to see how gates, parameters, and contracted gates are stored. Then check existing tests for graph building and circuit equality. Done when get_circuit returns an equivalent Circuit from the supplied parameters, with the boolean option controlling whether contracted gates are included.

Written by the indexing model from the issue text.

Description

documentation enhancement
Motivation

Since graph building can be done multiple times on the same propagator, it would be convenient to have a function that returns the underlying circuit

Proposed feature

get_circuit function that returns Circuit with all the gates and parameters (argument to get_circuit). Depending on the additional boolean keyword, it should include/not include contracted gates.

Proposed API or usage example (optional)

circuit = Circuit(...)
mp = MajoranaPropagator(...)
mp.build_graph(circuit)
circuit2 = mp.get_circuit(circuit.parameters)
assert circuit == circuit2
