Creation of quantum entangled states of Rydberg atoms via chirped adiabatic passage

Abstract Entangled states are crucial for modern quantum enabled technology which makes their creation key for future developments. In this paper, a robust quantum control methodology is presented to create entangled states of two typical classes, the W and the Greenberger–Horne–Zeilinger (GHZ). It...
