A theoretical investigation into the microwave spectroscopy of a phosphorus-donor charge-qubit in silicon: Coherent control in the Si:P quantum computer architecture
C. J. Wellard, L. C. L. Hollenberg, S. Das Sarma
We present a theoretical analysis of a microwave spectroscopy experiment on a charge qubit defined by a P donor pair in silicon, for which we calculate Hamiltonian parameters…
Identifying a Two-State Hamiltonian in the Presence of Decoherence
Jared H. Cole, Andrew D. Greentree, Daniel K. L. Oi +3
Mapping the system evolution of a two-state system allows the determination of the effective system Hamiltonian directly. We show how this can be achieved even if the system is dec…
Optically induced spin to charge transduction in donor spin read-out
M. J. Testolin, Andrew D. Greentree, C. J. Wellard +1
The proposed read-out configuration D+D- for the Kane Si:P architecture[Nature 393, 133 (1998)] depends on spin-dependent electron tunneling between donors, induced adiabatically b…
Spin transport and quasi 2D architectures for donor-based quantum computing
L. C. L. Hollenberg, A. D. Greentree, A. G. Fowler +1
Through the introduction of a new electron spin transport mechanism, a 2D donor electron spin quantum computer architecture is proposed. This design addresses major technical issue…
Donor Electron Wave Functions for Phosphorus in Silicon: Beyond Effective Mass Theory
C. J. Wellard, L. C. L. Hollenberg
We calculate the electronic wave-function for a phosphorus donor in silicon by numerical diagonalisation of the donor Hamiltonian in the basis of the pure crystal Bloch functions.…
Identifying an Experimental Two-State Hamiltonian to Arbitrary Accuracy
Jared H. Cole, Sonia G. Schirmer, Andrew D. Greentree +3
Precision control of a quantum system requires accurate determination of the effective system Hamiltonian. We develop a method for estimating the Hamiltonian parameters for some un…
