Excited states of defect lines in silicon: A first-principles study based on hydrogen cluster analogues
W. Wu, P. T. Greenland, A. J. Fisher +3
Excited states of a single donor in bulk silicon have previously been studied extensively based on effective mass theory. However, a proper theoretical description of the excited s…
Coherent Control of Rydberg States in Silicon
P. T. Greenland, S. A. Lynch, A. F. G. van der Meer +5
We demonstrate coherent control of donor wavefunctions in phosphorous-doped silicon. Our experiments take advantage of a free electron laser to stimulate and observe photon echoes…
Initializing, manipulating and storing quantum information with bismuth dopants in silicon
Gavin W. Morley, Marc Warner, A. Marshall Stoneham +4
A prerequisite for exploiting spins for quantum data storage and processing is long spin coherence times. Phosphorus dopants in silicon (Si:P) have been favoured as hosts for such…
Silicon as a model ion trap: time domain measurements of donor Rydberg states
N Q Vinh, P T Greenland, K Litvinenko +9
One of the great successes of quantum physics is the description of the long-lived Rydberg states of atoms and ions. The Bohr model is equally applicable to donor impurity atoms in…
Exchange in multi-defect semiconductor clusters: assessment of `control-qubit' architectures
W. Wu, P. T. Greenland, A. J. Fisher
We present a variational method to calculate the exchange interactions among donor clusters in a semiconductor. Such clusters are candidates for a so-called control-qubit architect…
