The Department of Microtechnology and Nanoscience focuses on research, innovation and education within the fields of future electronics, photonics, bio- and nanosystems. A close collaboration with Swedish and international partners within academy, industry and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.

Information about the division

The Quantum Device Physics Laboratory (QDP) at the department of Microtechnology and Nanoscience conducts research which extends over a variety of different topics. QDP is therefore divided into three sub groups: Experimental Mesoscopic Physics (EMP), Quantum Devices & Oxide Electronics (QuOx) and the Bolometer Group. Altogether, the QDP lab focuses on studying nano electronic components beyond classical electrodynamics, and explores possibilities to make quantum mechanical effects useful in practical devices.

As a PhD student, you will conduct experimental research on hybrid devices comprising topological insulators proximised with a superconductor.

Major responsibilities
The search for topological superconductivity in nanowires attracts a lot of interest due to potential applications in the field of quantum computation. An innovative route is to emulate unconventional superconductivity by building a junction from a TI and conventional superconducting electrodes. The successful applicant will build a transmon by embedding a TI-based Josephson junction inside a resonator that is used as a read-out device. Microwave photons are instrumental in the manipulation and measurement of quantum states in nanoelectronic structures. The recent advances in coupling solid-state quantum bits to superconducting microwave resonators, e.g. transmons, have resulted in improved state manipulation of qubits and drastic enhancements of coherence times. Such devices are powerful tools for detecting the dynamics of a variety of microscopic physical objects such as quasiparticle excitations or microscopic noise sources. This makes cryogenic microwave readout techniques very appealing for fundamental studies of microscopic physical systems in new emerging materials.

From the magnetic field dependence of the microwave transitions of such a topological junction embedded in a superconducting resonator, one will be able to discriminate between classical Andreev bound states and unconventional zero-energy states emerging from the topological protection.
