A new technical paper titled “Universal control of a six-qubit quantum processor in silicon” was just published by researchers at Delft University of Technology, QuTech and Netherlands Organization for Applied Scientific Research (TNO).
“We increase the number of qubits and simultaneously achieve respectable fidelities for universal operation, state preparation and measurement. We design, fabricate and operate a six-qubit processor with a focus on careful Hamiltonian engineering, on a high level of abstraction to program the quantum circuits, and on efficient background calibration, all of which are essential to achieve high fidelities on this extended system,” the paper states.
