Creation of Arbitrary Coherent Superposition States in Four-Level Systems
- State Key Laboratory of High Laser Physics, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Shanghai 201800 (China)
Using the technique of stimulated Raman adiabatic passage, we propose schemes for creating arbitrary coherent superposition states of atoms in four-level systems: a {lambda}-type system with twofold final states and a four-level ladder system. With the use of a control field, arbitrary coherent superposition states are created without the condition of multiphoton resonance. Suitable manipulation of detunings and the control field can create either a single state or any superposition states desired.
