Controlling Quantum Transport by State Synthesis in Ion Traps
Juan F. Poyatos, Gonzalo G. de Polavieja · Physical Review Letters · 1999
A procedure to control the quantum transport between classical regions is proposed. The scheme exploits the ability to synthesize arbitrary motional states in ion traps. Quantum barriers and passages to transport can be created selecting the relevant frequencies. This technique is then applied to stabilize the quantum motion onto classical structures or alter the dynamical tunneling in nonintegrable systems.
