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…
