  - "Over the past century, researchers have been fascinated by the quantum nature
    of the\r\nphysical world, initially striving to understand its fundamental principles
    and consequences, and\r\neventually progressing toward engineering systems that
    can control and manipulate quantum\r\nproperties. Today, we stand at the dawn
    of the quantum technology era. While some quantum\r\ntechnologies follow well-defined
    roadmaps, others are still in the exciting and uncertain early\r\nstages of development.
    In the fields of quantum computing and quantum simulation, research\r\nis being
    conducted across a wide variety of platforms. Each of these demonstrates control
    over\r\nquantum properties but also faces challenges in scaling up to the level
    of a mature technology.\r\nThis thesis explores some of the fundamental properties
    of hole spin qubits in planar germanium.\r\nSemiconductor spin qubits are considered
    strong candidates for the realization of quantum\r\nprocessors, owing to their
    long relaxation and coherence times, as well as their compatibility\r\nwith existing
    semiconductor industry infrastructure. Among these, hole spin qubits in planar\r\ngermanium
    are particularly promising. Their advantages include a large effective mass, which\r\neases
    fabrication constraints; inherent protection from hyperfine noise; and strong
    spin-orbit\r\ninteraction, which enables fast and purely electrical control. However,
    spin-orbit coupling also\r\nintroduces site-dependent variability across qubits,
    particularly in the g-tensors and spin-flip\r\ntunneling, which might cause that
    the quantization axes are not aligned. In this thesis, we\r\ninvestigate the tilt
    between the quantization axes of two hole spins hosted in a double quantum\r\ndot
    as a function of both the magnetic field direction and various electrostatic configurations,\r\ndemonstrating
    that both parameters influence this tilt. We conclude by introducing a machine-learning-assisted
    routine to automatically tune baseband spin qubits. This approach may prove\r\nto
    be a powerful tool for characterizing spin-orbit effects and gaining deeper insight
    into the\r\nphysics governing spin qubit behavior.\r\n@eng"
