      abstract     = {Germanium quantum wells emerged in recent years as a
                      promising platform for gate-defined spin qubits. The unique
                      properties of a two-dimensional hole gas in strained Ge,
                      with exceptional carrier mobility, compatibility with
                      silicon-based technologies, intrinsic spin-orbit-coupling,
                      and anisotropic g-tensor are key to this promise.
                      Particularly, the last two properties allow fast
                      all-electrical qubit driving and enable novel approaches for
                      spin qubit control. Additionally, the low effective mass and
                      Fermi level pinning to the valence band simplifies the
                      fabrication requirements of these devices. These
                      considerations make Germanium quantum wells an excellent
                      material choice for spin qubits. However, many of the
                      platform's physical properties are yet to be understood in
                      depth. Our measurements aim to uncover the microscopic
                      behavior of the quantum well stack. The initial focus is on
                      one and two qubit devices, to explore and understand the
                      anisotropy of spin-orbit interaction and g-factor tensor. We
                      report the current progress of our studies regarding these
                      devices.},
