A Quantum Information Theoretical Model for Quantum Secret Sharing Schemes
Hideki Imai, Joern Mueller-Quade, Anderson C. A. Nascimento +2
In this paper we introduce a quantum information theoretical model for quantum secret sharing schemes. We show that quantum information theory provides a unifying framework for the…
Monogamy of entanglement and other correlations
Masato Koashi, Andreas Winter
It has been observed by numerous authors that a quantum system being entangled with another one limits its possible entanglement with a third system: this has been dubbed the "mono…
Measuring Polynomial Invariants of Multi-Party Quantum States
M. S. Leifer, N. Linden, A. Winter
We present networks for directly estimating the polynomial invariants of multi-party quantum states under local transformations. The structure of these networks is closely related…
"Squashed Entanglement" - An Additive Entanglement Measure
Matthias Christandl, Andreas Winter
In this paper, we present a new entanglement monotone for bipartite quantum states. Its definition is inspired by the so-called intrinsic information of classical cryptography and…
A family of quantum protocols
I. Devetak, A. W. Harrow, A. Winter
We introduce two dual, purely quantum protocols: for entanglement distillation assisted by quantum communication (``mother'' protocol) and for entanglement assisted quantum communi…
On the existence of physical transformations between sets of quantum states
Anthony Chefles, Richard Jozsa, Andreas Winter
Let A = {rho_1,...,rho_n} be a given set of quantum states. We consider the problem of finding necessary and sufficient conditions on another set B = {sigma_1,...,sigma_n} that gua…
