Noise Correlations in a 1D Silicon Spin Qubit Array

Autor: Donnelly, M. B., Rowlands, J., Kranz, L., Hsueh, Y. L., Chung, Y., Timofeev, A. V., Geng, H., Singh-Gregory, P., Gorman, S. K., Keizer, J. G., Rahman, R., Simmons, M. Y.

Correlated noise across multi-qubit architectures is known to be highly detrimental to the operation of error correcting codes and the long-term feasibility of quantum processors. The recent discovery of spatially dependent correlated noise in multi-

Impact of measurement backaction on nuclear spin qubits in silicon

Autor: Monir, S., Osika, E. N., Gorman, S. K., Thorvaldson, I., Hsueh, Y. -L., Macha, P., Kranz, L., Reiner, J., Simmons, M. Y., Rahman, R.

Phosphorus donor nuclear spins in silicon couple weakly to the environment making them promising candidates for high-fidelity qubits. The state of a donor nuclear spin qubit can be manipulated and read out using its hyperfine interaction with the ele

Benchmarking high fidelity single-shot readout of semiconductor qubits

Autor: Keith, D., Gorman, S. K., Kranz, L., He, Y., Keizer, J. G., Broome, M. A., Simmons, M. Y.

Determination of qubit initialisation and measurement fidelity is important for the overall performance of a quantum computer. However, the method by which it is calculated in semiconductor qubits varies between experiments. In this paper we present
