Benchmarking high fidelity single-shot readout of semiconductor qubits
D. Keith, S. K. Gorman, L. Kranz +4
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 semi…
Two-Electron Spin Correlations in Precision Placed Donors in Silicon
M. A. Broome, S. K. Gorman, M. G. House +8
Substitutional donor atoms in silicon are promising qubits for quantum computation with extremely long relaxation and dephasing times demonstrated. One of the critical challenges o…
Singlet-triplet minus mixing and relaxation lifetimes in a double donor dot
S. K. Gorman, M. A. Broome, M. G. House +6
We measure singlet-triplet mixing in a precision fabricated double donor dot comprising of 2 and 1 phosphorus atoms separated by nm. We identify singlet and triplet-minu…
High Fidelity Single-Shot Singlet-Triplet Readout of Precision Placed Donors in Silicon
M. A. Broome, T. F. Watson, D. Keith +6
In this work we perform direct single-shot readout of the singlet-triplet states in exchange coupled electrons confined to precision placed donor atoms in silicon. Our method takes…
