Microwave-engineering of programmable XXZ Hamiltonians in arrays of Rydberg atoms [PDF]
, 2021 We use the resonant dipole-dipole interaction between Rydberg atoms and a periodic external microwave field to engineer XXZ spin Hamiltonians with tunable anisotropies.

Ultrafast energy exchange between two single Rydberg atoms on the nanosecond timescale [PDF]
Conference on Lasers and Electro-Optics, 2021 We observed a nanosecond-scale dynamics between two single atoms trapped in optical tweezers separated by ∼ 1 µm and excited to Rydberg state with picosecond laser pulses. This opens the path for ultrafast quantum computation.

Physics Letters A, 2009 We analyze bound states of an electron in the field of a positively charged nanoshell. We find that the binding and excitation energies of the system decrease when the radius of the nanoshell increases. We also show that the ground and the first excited states of this system have remarkably the same properties of the highly excited Rydberg states of a ...

Quantum Computation in a Hybrid Array of Molecules and Rydberg Atoms [PDF]
PRX Quantum, 2022 We show that an array of polar molecules interacting with Rydberg atoms is a promising hybrid system for scalable quantum computation. Quantum information is stored in long-lived hyperfine or rotational states of molecules which interact indirectly ...

Control and Entanglement of Individual Rydberg Atoms near a Nanoscale Device. [PDF]
Physical Review Letters, 2022 Coherent control of Rydberg atoms near dielectric surfaces is a major challenge due to the large sensitivity of Rydberg states to electric fields. We demonstrate coherent single-atom operations and two-qubit entanglement as close as 100 μm from a ...

Electric Rydberg-Atom Interferometry [PDF]
Physical Review Letters, 2019 An electric analogue of the longitudinal Stern-Gerlach matter-wave interferometer has been realized for atoms in Rydberg states with high principal quantum number, $n$. The experiments were performed with He atoms prepared in coherent superpositions of the $n=55$ and $n=56$ circular Rydberg states in zero electric field by a $ /2$ pulse of resonant ...

Increasing the decoherence rate of Rydberg polaritons due to accumulating dark Rydberg atoms
Physical Review Research, 2022 We experimentally observed an accumulative type of nonlinear attenuation and distortion of slow light, i.e., Rydberg polaritons, with the Rydberg state |32D_{5/2}〉 in the weak-interaction regime. The present effect of attenuation and distortion cannot be

A photonic entanglement filter with Rydberg atoms [PDF]
Nature Photonics, 2022 Devices capable of deterministically manipulating photonic entanglement are of paramount importance, because photons are ideal messengers for quantum information.
