Toffoli gate based on a three-body fine-structure-state-changing Förster resonance in Rydberg atoms
I. N. Ashkarin, I. I. Beterov, E. A. Yakshina +7
We have developed an improved scheme of a three-qubit Toffoli gate based on fine structure state changing three-body Stark-tuned Rydberg interaction. This scheme is a substantial i…
Application of adiabatic passage in Rydberg atomic ensembles for quantum information processing
I. I. Beterov, D. B. Tretyakov, V. M. Entin +4
We review methods for coherently controlling Rydberg quantum states of atomic ensembles using Adiabatic Rapid Passage and Stimulated Raman Adiabatic Passage. These methods are comm…
Fast three-qubit Toffoli quantum gate based on the three-body Förster resonances in Rydberg atoms
I. I. Beterov, I. N. Ashkarin, E. A. Yakshina +6
We propose a scheme of fast three-qubit Toffoli quantum gate for ultracold neutral-atom qubits. The scheme is based on the Stark-tuned three-body Förster resonances, which we have…
Two-qubit gates using adiabatic passage of the Stark-tuned Förster resonances in Rydberg atoms
I. I. Beterov, M. Saffman, E. A. Yakshina +5
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-tune…
Spectroscopy of cold rubidium Rydberg atoms for applications in quantum information
I. I. Ryabtsev, I. I. Beterov, D. B. Tretyakov +2
Atoms in highly excited (Rydberg) states have a number of unique properties which make them attractive for applications in quantum information. These are large dipole moments, life…
Simulated quantum process tomography of quantum gates with Rydberg superatoms
I. I. Beterov, M. Saffman, E. A. Yakshina +4
We have numerically simulated quantum tomography of single-qubit and two-qubit quantum gates with qubits represented by mesoscopic ensembles containing random numbers of atoms. Suc…
Jaynes-Cummings dynamics in mesoscopic ensembles of Rydberg-blockaded atoms
I. I. Beterov, T. Andrijauskas, D. B. Tretyakov +4
We show that Jaynes-Cummings dynamics can be observed in mesoscopic atomic ensembles interacting with a classical electromagnetic field in the regime of Rydberg blockade, where the…
Controlling the interactions of a few cold Rb Rydberg atoms by radiofrequency-assisted Förster resonances
D. B. Tretyakov, V. M. Entin, E. A. Yakshina +3
Long-range interactions between cold Rydberg atoms, which are used in many important applications, can be enhanced using Förster resonances between collective many-body states cont…
Quantum gates in mesoscopic atomic ensembles based on adiabatic passage and Rydberg blockade
I. I. Beterov, M. Saffman, E. A. Yakshina +8
We present schemes for geometric phase compensation in adiabatic passage which can be used for the implementation of quantum logic gates with atomic ensembles consisting of an arbi…
