An 11-qubit atom processor in silicon
Hermann Edlbauer, Junliang Wang, A. M. Saffat-Ee Huq +12
Phosphorus atoms in silicon are an outstanding platform for quantum computing as their nuclear spins exhibit coherence time over seconds. By placing multiple phosphorus atoms withi…
Grover's algorithm in a four-qubit silicon processor above the fault-tolerant threshold
Ian Thorvaldson, Dean Poulos, Christian M. Moehle +15
Spin qubits in silicon are strong contenders for realizing a practical quantum computer. This technology has made remarkable progress with the demonstration of single and two-qubit…
Impact of measurement backaction on nuclear spin qubits in silicon
S. Monir, E. N. Osika, S. K. Gorman +7
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…
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…
