DESCRIPTION:Prof. Dr. Andrea Hofmann\nOn the next talk in our Quantum Semi
 nar series\, Thursday June 1st\, we have the pleasure of having Prof. And
 rea Hofmann from the Department of Physics\, University of Basel\, talk ab
 out “Quantum Devices in Germanium heterostructures”. Location: BS 270\
 n\nAs last time\, Pizzas will be available in front of the auditorium\, b
 efore the seminar (11:45-12:15). All PhDs\, postdocs\, students\, and PIs 
 are welcome to join us. All PIs are welcome to suggest our next speakers.\
 n\nAbstract:\n\nHigh-quality semiconductor heterostructures build the basi
 c ingredient facilitating quantum transport experiments including the prom
 ising field of semiconductor spin qubits. The material used for the quantu
 m well (QW) determines the properties of the confined quantum states. Ge Q
 Ws have recently emerged as a suitable platform for fast spin qubits\, due
  to a combination of favorable properties of the confined states. The Ge p
 latform is furthermore interesting as it allows to investigate low-dimensi
 onal valence band states\, which are much less studied than conduction ban
 d states. Last but not least\, the Fermi level pinning close to the valenc
 e band enables inducing superconductivity via the proximity effect.\n\nIn 
 our lab\, we use semiconducting structures to build spin qubits\, and we m
 ake use of the proximity effect to build hybrid qubits. Eventually\, we wa
 nt to couple the different qubits via microwave resonator photons. Going t
 his path\, we will answer basic research questions by studying in detail t
 he quantum states and the distinct types of spin—orbit interactions occu
 rring in different devices.
