Lund Universityâs Quantum Information Group is seeking qualified applicants for a research position focused on developing a small quantum processor node, where the qubits consist of individual ions of rare-earth elements (lanthanides). Such a processor node is a key unit that can be used in several quantum technologies, including quantum computing and quantum communication.
A couple of key strengths of rare-earth materials are their very long coherence times and the fact that different ions can be distinguished by light, interacting at slightly different frequencies. This means that many qubits can be uniquely identified even if the processor node is only a few nanometers large. To detect the individual ions, the project uses an optical micro-cavity that leverages the Purcell effect to amplify the emission. All this leads to a high density of qubits and a strong capacity to integrate the processor into optical systems.
The work will be carried out in the Quantum Information Group at Lund University, which has a strong history of utilizing these materials for quantum technologies. The successful applicant will gain a beneficial Swedish employment, including a monthly salary of about â¬3000.
