SUMMARY:Gate tunable spin splitting of germanium quantum well Josephso
 n junctions\, Preliminary Exam\, Avani Vivrekar\, Physics PhD Graduate
  Student
DESCRIPTION:In my prelim exam\, I will discuss Andreev spin qubits\, a
  novel super-semi hybrid platform for quantum computation. Proximitize
 d germanium (Ge) heterostructures are a promising host platform for An
 dreev qubits due to their strong spin-orbit coupling\, high mobility\,
  and naturally low nuclear spin abundance. A key distinction between G
 e and traditional materials used for Andreev qubits\, such as indium a
 rsenide (InAs)\, is the form of their Rashba spin-orbit coupling\, whi
 ch is linear in momentum for InAs but cubic for Ge. In this talk\, I w
 ill compare the effects of linear versus cubic spin-orbit coupling on 
 the physics of Andreev qubits. I will also discuss the impact of charg
 e defects on Andreev spin qubits in both InAs and Ge and explore the i
 mplications of these analyses for implementing Andreev spin qubits usi
 ng Ge.
