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…
On the quantum, classical and total amount of correlations in a quantum state
Berry Groisman, Sandu Popescu, Andreas Winter
We give an operational definition of the quantum, classical and total amount of correlations in a bipartite quantum state. We argue that these quantities can be defined via the amo…
Lower bound on the number of Toffoli gates in a classical reversible circuit through quantum information concepts
Sandu Popescu, Berry Groisman, Serge Massar
The question of finding a lower bound on the number of Toffoli gates in a classical reversible circuit is addressed. A method based on quantum information concepts is proposed. The…
Reply to Comment on "Continuous quantum measurement: inelastic tunneling and lack of current oscillations"
T. M. Stace, S. D. Barrett
We reply to a comment by Averin and Korotkov http://uk.arxiv.org/abs/cond-mat/0404549 on Stace and Barrett, PRL 92, 136802 (2004) http://link.aps.org/abstract/PRL/v92/e136802, show…
