Atoms in highly excited (Rydberg) states have a number of unique properties which make
them attractive for applications in quantum information: large dipole moments, lifetimes, and …

The strong interaction between individual Rydberg atoms provides a powerful tool exploited
in an ever-growing range of applications in quantum information science, quantum …

Quantum gates and entanglement based on dipole–dipole interactions of neutral Rydberg
atoms are relevant to both fundamental physics and quantum information science. The …

We calculate interspecies Rydberg-Rydberg interaction strengths for the heavy alkali metals
Rb and Cs. The presence of strong Förster resonances makes interspecies coupling a …

Because of their strong and tunable interactions, Rydberg atoms can be used to realize fast
two-qubit entangling gates. We propose a generalization of a generic two-qubit Rydberg …

Quantum information processing with neutral atoms relies on Rydberg excitation for
entanglement generation. While the use of heavy divalent or open-shell elements, such as …

Extending optical nonlinearity into the extremely weak light regime is at the heart of quantum
optics, since it enables the efficient generation of photonic entanglement and …

We propose schemes of controlled-Z and controlled-not gates with ultracold neutral atoms
based on deterministic phase accumulation during double adiabatic passage of the Stark …

We report the experimental observation of a cross-Kerr nonlinearity in a free-space medium
based on resonantly excited, interacting Rydberg atoms and electromagnetically induced …
