Fast Rydberg antiblockade regime and its applications in quantum logic gates

SL Su, Y Gao, E Liang, S Zhang - Physical Review A, 2017 - APS
Unlike the Rydberg blockade regime, the Rydberg antiblockade regime (RABR) allows more
than one Rydberg atom to be excited, which can bring other interesting phenomena and …

Evidence of antiblockade in an ultracold Rydberg gas

T Amthor, C Giese, CS Hofmann, M Weidemüller - Physical review letters, 2010 - APS
We present the experimental observation of the antiblockade in an ultracold Rydberg gas
