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

In multi-level systems, the commonly used adiabatic elimination is a method for
approximating the dynamics of the system by eliminating irrelevant, nonresonantly coupled …

We iteratively apply a recently formulated adiabatic theorem for the strong-coupling limit in
finite-dimensional closed and open quantum systems. This allows us to improve …

Conditions to achieve an unusually strong Rydberg spin-exchange interaction are
investigated and proposed as a means to generate pairwise entanglement and realize a …

One can implement fast two-qubit entangling gates by exploiting the Rydberg blockade.
Although various theoretical schemes have been proposed, experimenters have not yet …

We present a theoretical model of a four-photon excitation process to the Rydberg state in
thermal atomic vapor where the motion-induced dephasing in the system is eliminated. This …

We present the experimental demonstration of interaction induced enhancement in Rydberg
excitation or Rydberg anti-blockade in thermal atomic vapor. We have used optical …

We investigate the possibility of realizing supersolid quantum phases in bosonic Rydberg-
excited quantum lattice gases in the presence of nonunitary processes, by simulating the …

We experimentally and theoretically study Bragg diffraction as a tool for large-momentum
transfer beam splitters in atom interferometry. A theoretical framework is developed to …

Photons do not interact in vacuum, as they carry neither mass nor charge. However,
controlled interactions can be mediated by optically nonlinear media. A paradigm studied in …
