Args:

control_radius: the maximum distance between qubits for a controlled
gate. Distance is measured in units of the indices passed into
the GridQubit constructor.

in parallel by a Z gate

in parallel by a local XY gate

parallel by a controlled gate. Must be less than or equal to the
lesser of max_parallel_z and max_parallel_xy
qubits: Qubits on the device, identified by their x, y location.
