Theoretical Analysis of a Possible Method to Quantum Communication of Exceed Velocity of Light

If the projection of two photon entangled state in two orthogonal state basis are not equal,the direction of observation of one photon would have influence on the probability distribution of the polarization state of the other photon, which affects the statistical results of a large number of photons. non-local communication can be realized with this method. To get these type of two photon entangled state, this paper designs a method: put the calcium atoms in strong magnetic field.According to the Zeeman effect,calcium atoms would have energy level splitting. Then if the angle between the direction of observation and magnetic field is acute angle, the π light of the calcium atoms’ cascade radiation from 4p2 1S0→4s4p 1P1→4s1 1S0 would meet the requirement. Thus we demonstrate the method of non fixed domain transfer information is feasible.
