Abstract: The disclosure relates to a qubit device and to methods of operating a qubit device. In one arrangement, a quantum well structure hosts a hole gas in a quantum well. Electrodes form a plurality of quantum dots in the hole gas and allow encoding of a unit of quantum information in hole spins in the quantum dots. X-rotations on the Bloch sphere can be implemented using a g-factor difference between hole spins and a low applied magnetic field. Z-rotations can be implemented using the exchange interaction.
