Entanglement generation and concentration via adiabatic evolution with trapped ions. (English) Zbl 1146.81307
Summary: We propose two schemes via adiabatic evolution of dark eigenstates in an ion trap system. One is an entanglement generation of multi-ion cluster states, the other is entanglement concentration via entanglement swapping. Our schemes are robust against moderate fluctuations of experimental parameters since we utilize the adiabatic passage in the main procedure. The current idea can be generalized to other systems.
