Coherence of Spin Qubits in Silicon
A. M. Tyryshkin, J. J. L. Morton, S. C. Benjamin +4
Given the effectiveness of semiconductor devices for classical computation one is naturally led to consider semiconductor systems for solid state quantum information processing. Se…
Line Broadening and Decoherence of Electron Spins in Phosphorus-Doped Silicon Due to Environmental 29^Si Nuclear Spins
Eisuke Abe, Akira Fujimoto, Junichi Isoya +2
Phosphorus-doped silicon single crystals with 0.19 % <= f <= 99.2 %, where f is the concentration of 29^Si isotopes, are measured at 8 K using a pulsed electron spin resonance tech…
Towards a fullerene-based quantum computer
Simon C Benjamin, Arzhang Ardavan, G Andrew D Briggs +12
Molecular structures appear to be natural candidates for a quantum technology: individual atoms can support quantum superpositions for long periods, and such atoms can in principle…
Electron spin relaxation of N@C60 in CS2
John J. L. Morton, Alexei M. Tyryshkin, Arzhang Ardavan +3
We examine the temperature dependence of the relaxation times of the molecules N@C60 and N@C70 (which comprise atomic nitrogen trapped within a carbon cage) in liquid CS2 solution.…
Electrical activation and electron spin coherence of ultra low dose antimony implants in silicon
T. Schenkel, A. M. Tyryshkin, R. de Sousa +7
We implanted ultra low doses (2x10^11 cm-2) of 121Sb ions into isotopically enriched 28Si and find high degrees of electrical activation and low levels of dopant diffusion after ra…
High Fidelity Single Qubit Operations using Pulsed EPR
John J. L. Morton, Alexei M. Tyryshkin, Arzhang Ardavan +3
Systematic errors in spin rotation operations using simple RF pulses place severe limitations on the usefulness of the pulsed magnetic resonance methods in quantum computing applic…
