Abstract
Section titled âAbstractâWe introduce a simple yet versatile protocol to inverse engineer the\ntime-dependent Hamiltonian in two- and three level systems. In the protocol, by\nutilizing a universal SU(2) transformation, a given speedup goal can be\nobtained with large freedom to select the control parameters. As an\nillustration example, the protocol is applied to perform population transfer\nbetween nitrogen-vacancy (NV) centers in diamond. Numerical simulation shows\nthat the speed of the present protocol is fast compared with that of the\nadiabatic process. Moreover, the protocol is also tolerant to decoherence and\nexperimental parameter fluctuations. Therefore, the protocol may be useful for\ndesigning an experimental feasible Hamiltonian to engineer a quantum system.\n
