Spin coherence as a function of depth for high-density ensembles of silicon vacancies in proton-irradiated 4H-SiC
P. G. Brereton, D. Puent, J. Vanhoy +2
Defects in wide-bandgap semiconductors provide a pathway for applications in quantum information and sensing in solid state materials. The silicon vacancy in silicon carbide has re…
Fast preparation of single hole spin in InAs/GaAs quantum dot in Voigt geometry magnetic field
T. M. Godden, J. H. Quilter, A. J. Ramsay +6
The preparation of a coherent heavy-hole spin via ionization of a spin-polarized electron-hole pair in an InAs/GaAs quantum dot in a Voigt geometry magnetic field is investigated.…
Coherent optical control of the spin of a single hole in a quantum dot
T. M. Godden, J. H. Quilter, A. J. Ramsay +7
We demonstrate coherent optical control of a single hole spin confined to an InAs/GaAs quantum dot. A superposition of hole spin states is created by fast (10-100 ps) dissociation…
Quantum state preparation in semiconductor dots by adiabatic rapid passage
Yanwen Wu, I. M. Piper, M. Ediger +5
Preparation of a specific quantum state is a required step for a variety of proposed practical uses of quantum dynamics. We report an experimental demonstration of optical quantum…
