Description
Full text: The Kane model for a silicon based quantum computer proposes that the nuclear spins of individual phosphorus dopant atoms be the qubits. An external voltage would control the phosphorus hyperfine field and hence the nuclear magnetic resonance frequency of the qubits. Here electron spin resonance is used to probe for changes in the phosphorus hyperfine field. Initial measurements on (bulk) P:Si wafers as a function of applied DC voltage at 5 K show no Stark shift. However, DC current measurements at 4.2 K show that this observation is not a fundamental problem but the result of slow time scale charge migration in the 1017 cm3 doped silicon.
