Pseudospin and Quantum Computation in Semiconductor Nanostructures
V. W. Scarola, K. Park, S. Das Sarma
We review the theoretical aspects of pseudospin quantum computation using vertically coupled quantum dots in the quantum Hall regime. We discuss the robustness and addressability o…
The Exchange Gate in Solid State Spin Quantum Computation: The Applicability of the Heisenberg Model
V. W. Scarola, S. Das Sarma
Solid state quantum computing proposals rely on adiabatic operations of the exchange gate among localized spins in nanostructures. We study corrections to the Heisenberg interactio…
Quantum Information Protectorates in Coupled Quantum Dot Exchange Gates
V. W. Scarola, S. Das Sarma
Using exact diagonalization we study the low energy Hilbert space of the two-electron, two-quantum dot artificial molecule under a perpendicular magnetic field. We show that electr…
Pseudospin Quantum Computation in Semiconductor Nanostructures
V. W. Scarola, K. Park, S. Das Sarma
We theoretically show that spontaneously interlayer-coherent bilayer quantum Hall droplets should allow robust and fault-tolerant pseudospin quantum computation in semiconductor na…
Even-Odd Effect in Spontaneously Coherent Bilayer Quantum Hall Droplets
K. Park, V. W. Scarola, S. Das Sarma
Using exact diagonalization in the disc geometry we predict a novel even-odd effect in the Coulomb blockade spectra of vertically coupled double quantum dots under an external magn…
The Phonon Drag Effect in Single-Walled Carbon Nanotubes
V. W. Scarola, G. D. Mahan
A variational solution of the coupled electron-phonon Boltzmann equations is used to calculate the phonon drag contribution to the thermopower in a 1-D system. A simple formula is…
