Simulation of Rydberg Ionization in Atomic Beams for FIB Optimization

Clelia Bastelica, Azer Trimeche, Colin Lopez, Matthieu Viteau et autres

This study explores the excitation and ionization of an atomic beam as a pathway to optimize focused ion beams (FIBs) for high-precision applications. Leveraging the unique advantages of Rydberg excitation followed by field ionization -- specifically its ability to minimize velocity and …

Splitting of the three-body Förster resonance in Rb Rydberg atoms as a measure of the dipole-dipole interaction strength

I. I. Ryabtsev, I. N. Ashkarin, Ilya I. Beterov, Denis B. Tretyakov et autres

Three-body F\"orster resonances controlled by a dc electric field are of interest for the implementation of three-qubit quantum gates with single atoms in optical traps using their laser excitation into strongly interacting Rydberg states. In our recent theoretical paper [Zh. Eksp. Teor. …

Investigation of three-body Förster resonance for various spatial configurations of the three interacting Rubidium Rydberg atoms

I. I. Ryabtsev, I. N. Ashkarin, Ilya I. Beterov, Elena A. Yakshina et autres

Three-body Förster resonances controlled by a dc electric field are of interest for the implementation of three-qubit quantum gates with single atoms captured in optical traps and laser-excited into strongly interacting Rydberg states. In Ref. [P. Cheinet et al., Quantum Electronics 50(3), …

Long-range C C Φ gates via radio-frequency-induced Förster resonances

I. N. Ashkarin, S. Lepoutre, P. Pillet, Ilya I. Beterov et autres

Registers of trapped neutral atoms, excited to Rydberg states to induce strong long-distance interactions, are extensively studied for direct applications in quantum computing. Here we present a C C Φ quantum phase gate protocol based on radio-frequency-induced Förster resonant interactions in the …

Control system for ion Penning traps at the AEgIS experiment at CERN

Dorota Nowicka, Benedikt Bergmann, G. Bonomi, Roberto Sennen Brusa et autres

The AEgIS experiment located at the Antiproton Decelerator at CERN aims to measure the gravitational fall of a cold antihydrogen pulsed beam. The precise observation of the antiatoms in the Earth gravitational field requires a controlled production and manipulation of antihydrogen. The …

Development of a detector for inertial sensing of positronium at AEḡIS (CERN)

L. T. Glöggler, R. Caravita, Benedikt Bergmann, G. Bonomi et autres

The primary goal of the AEgIS collaboration at CERN is to measure the gravitational acceleration on neutral antimatter. Positronium (Ps), the bound state of an electron and a positron, is a suitable candidate for a force-sensitive inertial measurement by means of deflectometry/interferometry. …

Toffoli gate based on a three-body fine-structure-state-changing Förster resonance in Rydberg atoms

I. N. Ashkarin, Ilya I. Beterov, Elena A. Yakshina, Denis B. Tretyakov et autres

We have developed an improved scheme of a three-qubit Toffoli gate based on a fine-structure-state-changing three-body Stark-tuned Rydberg interaction. This scheme is a substantial improvement of our previous proposal [I. I. Beterov et al., Phys. Rev. A 98, 042704 (2018)]. Due to …

High-resolution MCP-TimePix3 imaging/timing detector for antimatter physics

L. T. Glöggler, R. Caravita, M. Auzins, Benedikt Bergmann et autres

Abstract We present a hybrid imaging/timing detector for force sensitive inertial measurements designed for measurements on positronium, the metastable bound state of an electron and a positron, but also suitable for applications involving other low intensity, low energy beams of neutral (antimatter)-atoms, …
