Quantum Entangled State Controlled By Ultrashort laser
With method of the the density matrix elements, study the interaction of ultrashort laser pulse with two entangled two-level systems, and the coherent dynamical properties under the model of semiclassical theoretics, analyze the transition of the quantum states using quantum information processing The result show that, when light drive on one of the atoms, the concurrence of the two two-level atoms change along with the initial state change, and along with the pulse area change. Meanwhile, changing the area of ultrashort laser pulse area to cause the Bell state interconversion, achieve to the quantum state operation and the control.
