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…
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…
