Fast Generation of Four-Dimensional Entanglement Between Two Spatially Separated Atoms via Shortcuts to Adiabatic Passage

摘要

We propose an efficient scheme for fast generation of four-dimensional entanglement between two atoms trapped in two cavities connected by a fiber via invariant-based shortcut to adiabatic passage. By means of quantum Zeno dynamics, the technique of invariant-based shortcut is applied for the generation of two-atom four-dimensional entanglement. Numerical simulations demonstrate that the scheme is robust against the decoherence caused by the atomic spontaneous emission, photon leakage, and variation in the parameters. Thus, the four-dimensional entanglement may be generated with a high fidelity under the current experimental technology.
