WebRydberg: [noun] the Rydberg constant especially when expressed in energy terms with maximum possible value of about 2.179 × 10−11 ergs. WebThis interaction between pairs of Rydberg atoms has proven to be a key feature for diverse applications in quan-tum information processing and quantum simulation [11]. A particularly important concept is the Rydberg blockade [12], where the excitation of two or more atoms to a Rydberg state is prevented due to the interaction. The Rydberg
