  - "The new era of Ge has opened up new possibilities in quantum computing. The maturity
    of Ge\r\nspin qubits is unquestioned, while hybrid semiconductor-superconductor
    Ge circuits are on track\r\nto enter the game. Gate-tunable transmons (gatemons)
    employing semiconductor Josephson\r\njunctions have recently emerged as building
    blocks for such hybrid quantum circuits. In this\r\nthesis, we present a gatemon
    fabricated in planar Germanium. We induce superconductivity\r\nin a two-dimensional
    hole gas by evaporating aluminum atop a thin spacer, which separates\r\nthe superconductor
    from the Ge quantum well. The Josephson junction is then integrated\r\ninto an
    Xmon circuit and capacitively coupled to a transmission line resonator. We showcase\r\nthe
    qubit tunability in a broad frequency range with resonator and two-tone spectroscopy.\r\nTime-domain
    characterizations reveal energy relaxation and coherence times up to 75 ns. Our\r\nresults,
    combined with the recent advances in the spin qubit field, pave the way towards
    novel\r\nhybrid and protected qubits in a group IV, CMOS-compatible material.@eng"
