Generation of singlet states with Rydberg blockade mechanism and driven by adiabatic passage

Generation of singlet states with Rydberg blockade mechanism and driven by adiabatic passage A single state is a special state that entangles multi-state quantum systems and plays a significant role in the field of quantum computation.

Abstract

A single state is a special state that entangles multi-state quantum systems and plays a significant role in the field of quantum computation. In this paper, we propose a scheme to realize the generation of single states for Rydberg atoms, where one Rydberg atom is trapped in an optical potential and the others are trapped in an adjacent optical potential. Moreover, combining Rydberg blockade and adiabatic-passage technologies, an N-atom singlet state can be generated with the interaction of an N-dimensional Rydberg atom and an ( $$N-1$$ N - 1 )-atom singlet state. Compared to previous schemes, the advantage of our proposal is that an N-particle N-level singlet state with $$N\ge 3$$ N ≥ 3 may be realized more simply.
