Comparative assessment of germanium-based spin-qubit modalities: donor, acceptor, gate-defined hole, and gate-defined electron platforms
Gate-defined hole spin qubits in germanium currently combine the best all-electrical control, demonstrated multiqubit operation, and scalability path among the four modalities compared.
