Chalmers University of Technology, Sweden call for applications for PhD Studentship Position in Department of Microtechnology and Nanoscience

Study Subject: Superconducting Quantum Circuits
Employer: Chalmers University of Technology
Level: PhD
Scholarship Description: We are looking for a motivated PhD student to be part of our experimental research on macroscopic quantum effects in nanoscaled cuprate superconductors. The position will be placed at the Quantum Device Physics Laboratory in the Department of Microtechnology and Nanoscience at Chalmers University of Technology.
The ability to engineer quantum systems can open up the way to new great opportunities. The experimental and theoretical investigation of superconducting artificial two level systems has developed as a rich, exciting field within the framework of quantum computing and cryptography. Far more interesting, the design of such artificial two level quantum systems (also known as quantum bits) can be used to study fundamental physics in fields ranging from quantum optics to solid-state physics in previously inaccessible regimes. In this context we want to tackle one of the main unresolved problems in solid-state physics: The microscopic origin of the complex properties of High critical Temperature Superconductors (HTS). Despite the numerous attempts to explain the true nature of superconductivity in these fascinating materials, it still remains one of the most “burning” topics in condensed matter physics. It is believed that its excitations hold the secret of its nature. The project aims at a deeper understanding of quantum circuitries made of the high critical temperature superconductor (HTS) YBa2Cu3O7-x with potential applications ranging from quantum computing to solid-state physics research in previously inaccessible regimes. The focus will be on material specific decoherence effects coming from the dielectrics involved in the fabrication process and the superconductor itself. In the latter case the project will be devoted to the experimental investigation of the low temperature excitation spectra of HTS by using two-level quantum systems. We will use a HTS Josephson junction, acting as a two level system, embedded in a superconducting resonator. This experiment will deliver detailed information about the quasiparticle spectrum of HTS, giving access to unresolved issues on the nature of superconductivity in these materials.
