Cerenkov generation of high-frequency confined acoustic phonons in quantum wells
S. M. Komirenko, K. W. Kim, A. A. Demidenko +2
We analyze the Cerenkov emission of high-frequency confined acoustic phonons by drifting electrons in a quantum well. We find that the electron drift can cause strong phonon amplif…
Progressive suppression of spin relaxation in 2D channels of finite width
A. A. Kiselev, K. W. Kim
We have investigated spatio-temporal kinetics of electron spin polarization in semiconductor narrow 2D strip and explored the ability to manipulate spin relaxation. Information abo…
NMR quantum computation with indirectly coupled gates
David Collins, K. W. Kim, W. C. Holton +2
An NMR realization of a two-qubit quantum gate which processes quantum information indirectly via couplings to a spectator qubit is presented in the context of the Deutsch-Jozsa al…
An optically driven quantum dot quantum computer
G. D. Sanders, K. W. Kim, W. C. Holton
We propose a quantum computer structure based on coupled asymmetric single-electron quantum dots. Adjacent dots are strongly coupled by means of electric dipole-dipole interactions…
