Laser system for experiments with qubits based on Rydberg cesium atoms

The laser system for experiments with qubits based on Rydberg cesium atoms enables a broad spectrum of new research and development that was previously inaccessible: - Development of quantum computers with ensembles of cold atoms, where each ensemble represents a qubit. - Development of a fast and reliable preparation of qubits in arbitrary superposition states of 0 and 1. - Development of a fast method for reading out qubits. - Research into the physics of Rydberg atoms and the application of the Rydberg blockade mechanism in quantum devices. - The possibility of using the laser system for the manipulation of qubits based on ensembles of cold atoms as well as for individual atoms.

The research equipment represents an upgrade of the experimental system for cooling and trapping cesium atoms that we have developed and built over the last ten years in the Laboratory for cold atoms at the Jožef Stefan Institute. Once the upgrade is fully completed (expected by mid-2024), this experimental equipment will be integrated into the existing experimental system. Team members from the Laboratory for cold atoms will have priority access to the research equipment. For researchers from public research institutes and public universities, use will be possible via joint projects (including informal collaboration) and is free of charge. For collaborations with industry, we will adhere to the rules outlined in the "Pravila za oblikovanje cen za uporabo raziskovalne opreme, obveščanje in poročanje o uporabi raziskovalne opreme", No. 007-5/2023-1 dated May 3, 2023.
