RLZ2Gate

class RLZ2Gate(chi, label=None)

Evolution of a coherent spin under the twisting dynamic generated by Lz^2’.

The generating Hamiltonian of the LZ2 gate is

\(H = \chi L_z^2\)

where \(\chi\) is the free gate parameter.

Circuit symbol:

     ┌───────────┐
q_0: ┤ RLZ2(chi) ├
     └───────────┘
