On the entanglement concentration of three-partite states
Berry Groisman, Noah Linden, Sandu Popescu
We investigate the concentration of multi-party entanglement by focusing on simple family of three-partite pure states, superpositions of Greenberger-Horne-Zeilinger states and sin…

Population inversion of driven two-level systems in a structureless bath
T. M. Stace, A. C. Doherty, S. D. Barrett
We derive a master equation for a driven double-dot damped by an unstructured phonon bath, and calculate the spectral density. We find that bath mediated photon absorption is impor…

Quantum Computing with Spin Qubits Interacting Through Delocalized Excitons: Overcoming Hole Mixing
Brendon W. Lovett, Ahsan Nazir, Ehoud Pazy +3
As a candidate scheme for controllably coupled qubits, we consider two quantum dots, each doped with a single electron. The spin of the electron defines our qubit basis and trion s…
