Qubits made by advanced semiconductor manufacturing
A. M. J. Zwerver, T. Krähenmann, T. F. Watson +26
Full-scale quantum computers require the integration of millions of quantum bits. The promise of leveraging industrial semiconductor manufacturing to meet this requirement has fuel…
Spatial Noise Correlations in a Si/SiGe Two-Qubit Device from Bell State Coherences
Jelmer M. Boter, Xiao Xue, Tobias S. Krähenmann +10
We study spatial noise correlations in a Si/SiGe two-qubit device with integrated micromagnets. Our method relies on the concept of decoherence-free subspaces, whereby we measure t…
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…
A programmable two-qubit quantum processor in silicon
T. F. Watson, S. G. J. Philips, E. Kawakami +9
With qubit measurement and control fidelities above the threshold of fault-tolerance, much attention is moving towards the daunting task of scaling up the number of physical qubits…
Mapping the Chemical Potential Landscape of a Triple Quantum Dot
M. A. Broome, S. K. Gorman, J. G. Keizer +4
We investigate the non-equilibrium charge dynamics of a triple quantum dot and demonstrate how electron transport through these systems can give rise to non-trivial tunnelling path…
