Quantum information can be negative
Michal Horodecki, Jonathan Oppenheim, Andreas Winter
Given an unknown quantum state distributed over two systems, we determine how much quantum communication is needed to transfer the full state to one system. This communication meas…
Entanglement of assistance and multipartite state distillation
John A. Smolin, Frank Verstraete, Andreas Winter
We find that the asymptotic entanglement of assistance of a general bipartite mixed state is equal to the smaller of its two local entropies. Our protocol gives rise to the asympto…
Implications of Superstrong Nonlocality for Cryptography
Harry Buhrman, Matthias Christandl, Falk Unger +2
Non-local boxes are hypothetical ``machines'' that give rise to superstrong non-local correlations, leading to a stronger violation of Bell/CHSH inequalities than is possible withi…
Classical Capacity of Quantum Binary Adder Channels
Gleb V. Klimovitch, Andreas Winter
We analyze the quantum binary adder channel, i.e. the quantum generalization of the classical, and well-studied, binary adder channel: in this model qubits rather than classical bi…
Uncertainty, Monogamy, and Locking of Quantum Correlations
Matthias Christandl, Andreas Winter
Squashed entanglement and entanglement of purification are quantum mechanical correlation measures and defined as certain minimisations of entropic quantities. We present the first…
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…
