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…

K. -L. Pham, S. Lepoutre, P. Pillet +7
Three body resonant interactions between Rydberg atoms are considered in order to perform few-body quantum gates. So far, the resonances found in cesium or rubidium atoms relied on…
Long-range gates via radio-frequency-induced Förster resonances
I. N. Ashkarin, S. Lepoutre, P. Pillet +3
Registers of trapped neutral atoms, excited to Rydberg states to induce strong long-distance interactions, are extensively studied for direct applications in quantum computing. Her…

Direct Observation of Second Order Atom Tunnelling
S. Foelling, S. Trotzky, P. Cheinet +5
Tunnelling of material particles through a classically impenetrable barrier constitutes one of the hallmark effects of quantum physics. When interactions between the particles comp…
Time-resolved Observation and Control of Superexchange Interactions with Ultracold Atoms in Optical Lattices
S. Trotzky, P. Cheinet, S. Fölling +7
Quantum mechanical superexchange interactions form the basis of quantum magnetism in strongly correlated electronic media. We report on the direct measurement of superexchange inte…

Cold Rydberg atoms subject to long-range dipole-dipole interactions represent a particularly interesting system for exploring few-body interactions and probing the transition from…

In atom interferometers based on two photon transitions, the delay induced by the difference of the laser beams paths makes the interferometer sensitive to the fluctuations of the…
