Researchers at the Rzhanov Institute have successfully mapped 3D electric fields around single rubidium Rydberg atoms using eight electrodes within an ultrahigh-vacuum cell. This precise control over field manipulation and stray compensation is a critical hardware advancement for scaling neutral-atom quantum computing architectures that rely on Rydberg excitation to generate entanglement. The technique validates theoretical calculations while simplifying calibration processes essential for building robust, large-scale quantum simulators.
Rzhanov Institute Maps Electric Fields of Single Rydberg Atoms
Researchers at Rzhanov Institute of Semiconductor Physics SB RAS created three-dimensional maps of electric fields around single rubidium Rydberg atoms.
Researchers at the Rzhanov Institute of Semiconductor Physics SB RAS, alongside collaborators from Novosibirsk State University and Saint-Petersburg State University, have achieved precise three-dimensional control over the electric field surrounding a single rubidium Rydberg atom. The work demonstrates the ability to manipulate the atom within an ultrahigh-vacuum glass cell using eight electrodes, a configuration essential for advancing quantum computing and simulation with neutral atoms. This research utilizes a technique called three-photon Stark spectroscopy. The measured three-photon spectra exhibit Stark shifts and…
