Control and readout topology for spin qubits KU Leuven
An integrated system (201) for quantum computation is provided, including at least: one semiconductor spin quantum bit (210), qubit; a feedline (240) configured to act as an electron spin resonance, ESR, antenna for control of the at least one qubit; at least one resonator (220_j), and a ground plane (250) common to both the feedline and the at least one resonator. The at least one resonator is capacitively coupled to the feedline, and configured for readout of said at least one qubit via the feedline. The feedline and the at least one resonator are arranged in adjacent layers separated by at ...
