Description
During the writing of #621 it became apparent that the new version of cirq 0.13.0 had changed the way gates are decomposed. Past quantumlib/Cirq#4167 some gates were decomposed into 3 qubit gates, which are not currently supported. Thus, #621 bypassed Cirq's default decomposition as a work around.
However, the work-around shouldn't say forever. Instead, we should:
- Handle 3-qubit gates
- Revert the work-around

Research direction
Start by reviewing issue #621 and the Cirq 0.13.0 decomposition behavior described here. Trace where the current workaround bypasses Cirq's default decomposition, then determine how 3-qubit gates are represented and supported. Done means 3-qubit gates are handled and the workaround from #621 is reverted.
