  text: In recent years, hybrid semiconductor–superconductor qubits have emerged as
    a compelling alternative to more traditional qubit platforms, owing to their unique
    combination of material properties and device-level tunability. A key feature
    of these systems is their gate-tunable Josephson coupling, which enables the realization
    of superconducting qubit architectures with full electric field control and which
    offers a promising route toward scalable and low-crosstalk quantum processors.
    One of the central motivations behind this approach is the possibility of unifying
    the advantages of superconducting and spin-based qubits. This approach to creating
    hybrid qubits can be achieved, for example, by encoding quantum information in
    the spin degree of freedom of a quasiparticle occupying an Andreev bound state,
    thereby combining long coherence times with fast and flexible control. Recent
    progress has been further accelerated by the bottom-up engineering of Andreev
    bound states into coupled quantum dot arrays, leading to the realization of novel
    device architectures such as minimal Kitaev chains hosting (poor man’s) Majorana
    states, precursors of topologically protected Majorana zero modes, and, very recently,
    to the first coherent control of a Majorana parity qubit. In parallel, alternative
    strategies have focused on the design of Hamiltonian-protected hybrid qubits,
    including Cooper pair parity qubits and fluxon parity qubits, which aim to enhance
    robustness against local noise and decoherence. These approaches leverage the
    interplay between superconducting phase dynamics and the discrete charge or flux
    degrees of freedom in hybrid junctions. In this article, we review recent theoretical
    and experimental advances in the development of semiconductor–superconductor hybrid
    qubits. We provide a comprehensive overview of the underlying physical mechanisms,
    device implementations, and emerging architectures, with particular emphasis on
    their potential to enable (topologically) protected quantum information processing.
    While many of these qubit designs remain at the proof-of-concept stage, the rapid
    pace of progress suggests that practical demonstrations may be within reach in
    the near future.
