The Trapped Ion Quantum Technology group at Stockholm University invites applications for a postdoctoral position on our trapped Rydberg ion project. The successful applicant will work on trapped ion experiments to perform fast quantum gates and quantum algorithms via Rydberg interaction.
Trapped Rydberg ions are a new system for quantum computation. By laser pulses the ions’ outermost electron is excited to a high-lying Rydberg orbital [1]. Such Rydberg ions are million times bigger than ions in the ground state, and due to their size obtain very peculiar properties. Trapped ions can be entangled via a strong Rydberg interaction in less than a microsecond [2]. This method supports fast entangling gates in large ions crystals, thus enabling a fast trapped ion quantum computer or quantum simulator.
The experimental postdoctoral project will take place in the Trapped Ion Quantum Technology group at Stockholm University and is financed by the Wallenberg Centre for Quantum Technology - WACQT.
