Recipes for spin-based quantum computing
Veronica Cerletti, W. A. Coish, Oliver Gywat +1
Technological growth in the electronics industry has historically been measured by the number of transistors that can be crammed onto a single microchip. Unfortunately, all good th…
Non-Markovian dynamics of a localized electron spin due to the hyperfine interaction
W. A. Coish, Daniel Loss
We review our theoretical work on the dynamics of a localized electron spin interacting with an environment of nuclear spins. Our perturbative calculation is valid for arbitrary po…
Entanglement transfer from electron spins to photons in spin light-emitting diodes containing quantum dots
Veronica Cerletti, Oliver Gywat, Daniel Loss
We show that electron recombination using positively charged excitons in single quantum dots provides an efficient method to transfer entanglement from electron spins onto photon p…
Cluster States From Heisenberg Interaction
Massoud Borhani, Daniel Loss
We show that a special type of entangled states, cluster states, can be created with Heisenberg interactions and local rotations in 2d steps where d is the dimension of the lattice…
Zitterbewegung of electronic wave packets in semiconductor nanostructures
John Schliemann, Daniel Loss, R. M. Westervelt
We study the zitterbewegung of electronic wave packets in III-V zinc-blende semiconductor quantum wells due to spin-orbit coupling. Our results suggest a direct experimental proof…
Controlling Spin Qubits in Quantum Dots
Hans-Andreas Engel, L. P. Kouwenhoven, Daniel Loss +1
We review progress on the spintronics proposal for quantum computing where the quantum bits (qubits) are implemented with electron spins. We calculate the exchange interaction of c…
