Spin qubits in graphene quantum dots
B. Trauzettel, Denis V. Bulaev, Daniel Loss +1
We propose how to form spin qubits in graphene. A crucial requirement to achieve this goal is to find quantum dot states where the usual valley degeneracy in bulk graphene is lifte…
Quantum versus classical hyperfine-induced dynamics in a quantum dot
W. A. Coish, E. A. Yuzbashyan, B. L. Altshuler +1
In this article we analyze spin dynamics for electrons confined to semiconductor quantum dots due to the contact hyperfine interaction. We compare mean-field (classical) evolution…
Exchange-controlled single-electron-spin rotations in quantum dots
W. A. Coish, Daniel Loss
We show theoretically that arbitrary coherent rotations can be performed quickly (with a gating time ~1 ns) and with high fidelity on the spin of a single confined electron using c…
Spin-spin coupling in electrostatically coupled quantum dots
Mircea Trif, Vitaly N. Golovach, Daniel Loss
We study the spin-spin coupling between two single-electron quantum dots due to the Coulomb and spin-orbit interactions, in the absence of tunneling between the dots. We find an an…
Electric Dipole Spin Resonance for Heavy Holes in Quantum Dots
Denis V. Bulaev, Daniel Loss
We propose and analyze a new method for manipulation of a heavy hole spin in a quantum dot. Due to spin-orbit coupling between states with different orbital momenta and opposite sp…
Sequential Tunneling through Molecular Spin Rings
Jörg Lehmann, Daniel Loss
We consider electrical transport through molecules with Heisenberg-coupled spins arranged in a ring structure in the presence of an easy-axis anisotropy. The molecules are coupled…
