DEVICE FOR MANIPULATING QUBITS FOR A SEMICONDUCTOR SPIN QUBIT QUANTUM COMPUTER
Abstract
A manipulation zone for a spin-qubit quantum processor comprising a plurality of gate electrodes (50b-1, 50b-2) arranged on a semiconductor heterostructure (12). The plurality of gate electrodes comprises a first finger gate assembly (50b-1) arranged at a first path (451) in the semiconductor heterostructure and a second finger gate assembly (50b-2) arranged at a second path (452) in the semiconductor heterostructure. The first path and the second path meet at an interface (25). The first finger gate assembly and the second finger gate assembly are configured to be supplied with at least one voltage V, to move along the first path formed and/or the second path at least one qubit, and/or to manipulate a current spin state of the at least one qubit located at the first path and/or the second path. The spin-qubit device further comprises local magnets (35-1, 35-2) and an external magnetic field. An embodiment uses top gates (50d in fig. 3D).
