Logic gates using high Rydberg states [PDF]

Proceedings of the National Academy of Sciences, 2001
Connected logic gates can be operated on the levels of one molecule by making use of the special properties of high Rydberg states. Explicit experimental results for the NO molecule are provided as an example. A number of other options, including that of several gates concatenated so as to operate as a full adder, are discussed.

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

Laser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

All-optical Stückelberg spectroscopy of strongly driven Rydberg states

Physical Review Research, 2022
The AC Stark shift of electronic levels is ubiquitous in the interaction of intense light fields with atoms and molecules. As the light intensity changes on the rising and falling edges of a femtosecond laser pulse, it shifts the Rydberg states in and ...

Proposal for the determination of nuclear masses by high-precision spectroscopy of Rydberg states

, 2010
The theoretical treatment of Rydberg states in one-electron ions is facilitated by the virtual absence of the nuclear-size correction, and fundamental constants like the Rydberg constant may be in the reach of planned high-precision spectroscopic ...

Dynamics of Purification in Cu2O

physica status solidi (b), EarlyView.
Rydberg excitons in Cu2O have been shown to be highly efficient in neutralizing and screening charged impurities, which is referred to as purification. In this manuscript, the dynamics of the purification process are investigated under varying probe exciton‐ and plasma density. The transient absorption of Rydberg excitons is analyzed and five different

Electromagnetically Induced Transparency Spectra of ⁶Li Rydberg Atoms

Photonics, 2023
Rydberg atoms possess highly excited valence electrons that are far away from atomic cations. Compared with ground states, Rydberg states are excited states with a high principal quantum number n that exhibit large electric dipole moments and have a ...

Blinking Optical Tweezers for Atom Rearrangements

Advanced Quantum Technologies, EarlyView.
The work introduces an energy‐efficient method for holding and rearranging an N ×$\times$ M array of atoms using only N optical tweezers, using just 1M of the optical power per atom. In the proof‐of‐concept experiments, single blinking tweezer holds M = 9 atoms and further facilitates rearrangement M = 4 ∼$\sim$ 5 atoms in various configurations ...

Adiabatic passage of radiofrequency-assisted Forster resonances in Rydberg atoms for two-qubit gates and generation of Bell states

, 2017
High-fidelity entangled Bell states are of great interest in quantum physics. Entanglement of ultracold neutral atoms in two spatially separated optical dipole traps is promising for implementation of quantum computing and quantum simulation and for ...
