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…
Connections between relative entropy of entanglement and geometric measure of entanglement
Tzu-Chieh Wei, Marie Ericsson, Paul M. Goldbart +1
As two of the most important entanglement measures--the entanglement of formation and the entanglement of distillation--have so far been limited to bipartite settings, the study of…
Selective spin coupling through a single exciton
A. Nazir, B. W. Lovett, S. D. Barrett +2
We present a novel scheme for performing a conditional phase gate between two spin qubits in adjacent semiconductor quantum dots through delocalized single exciton states, formed t…
Entanglement generation in persistent current qubits
J. F. Ralph, T. D. Clark, T. P. Spiller +1
In this paper we investigate the generation of entanglement between two persistent current qubits. The qubits are coupled inductively to each other and to a common bias field, whic…
