Molecular orbital calculations of two-electron states for P donor solid-state spin qubits
L. M. Kettle, Hsi-Sheng Goan, Sean C. Smith
We theoretically study the Hilbert space structure of two neighbouring P donor electrons in silicon-based quantum computer architectures. To use electron spins as qubits, a crucial…

Effects of J-gate potential and interfaces on donor exchange coupling in the Kane quantum computer architecture
L. M. Kettle, H. -S. Goan, Sean C. Smith +2
We calculate the electron exchange coupling for a phosphorus donor pair in silicon perturbed by a J-gate potential and the boundary effects of the silicon host geometry. In additio…

Numerical study of hydrogenic effective mass theory for an impurity P donor in Si in the presence of an electric field and interfaces
L. M. Kettle, H. S. Goan, Sean C. Smith +3
In this paper we examine the effects of varying several experimental parameters in the Kane quantum computer architecture: A-gate voltage, the qubit depth below the silicon oxide b…
