Shuttling a single charge across a one-dimensional array of silicon quantum dots
Shuttling a single charge across a one-dimensional array of silicon quantum dots
Significant advances have been made towards fault-tolerant operation of silicon spin qubits, with single qubit fidelities exceeding 99.9%, several demonstrations of two-qubit gates based on exchange coupling, and the achievement of coherent single spin-photon coupling. Coupling arbitrary pairs of spatially separated qubits in a quantum register poses a significant challenge …
