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…
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…
Extracting inter-dot tunnel couplings between few donor quantum dots in silicon
Samuel K. Gorman, Matthew A. Broome, Joris G. Keizer +4
The long term scaling prospects for solid-state quantum computing architectures relies heavily on the ability to simply and reliably measure and control the coherent electron inter…
The impact of nuclear spin dynamics on electron transport through donors
Samuel K. Gorman, Matthew A. Broome, William J. Baker +1
We present an analysis of electron transport through two weakly coupled precision placed phosphorus donors in silicon. In particular, we examine the (1,1) to (0,2) charge transitio…
