Extending Bell inequalities to more parties
Yu-Chun Wu, Piotr Badziag, Marcin Wieśniak +1
We describe a method of extending Bell inequalities from to parties and formulate sufficient conditions for our method to produce tight inequalities from tight inequaliti…
Experimentally friendly geometrical criteria for entanglement
P. Badziag, C. Brukner, W. Laskowski +2
We present an intuitive geometrical entanglement criterion. It allows formulation of simple and experimentally friendly sufficient conditions for entanglement. The conditions are i…
No-local-broadcasting theorem for quantum correlations
Marco Piani, Pawel Horodecki, Ryszard Horodecki
We prove that the correlations present in a multipartite quantum state have an \emph{operational} quantum character as soon as the state does not simply encode a multipartite class…
Nonmaximally entangled states can be better for multiple linear optical teleportation
Joanna Modlawska, Andrzej Grudka
We investigate multiple linear optical teleportation in the Knill-Laflamme-Milburn scheme with both maximally and nonmaximally entangled states. We show that if the qubit is telepo…
Entanglement-swapping boxes and their communication properties
Andrzej Grudka, Michal Horodecki, Pawel Horodecki +2
We pose the fundamental question of communication properties of primitives irrespectively of their implementation. To illustrate the idea we introduce the concept of entanglement-s…
Unconditional privacy over channels which cannot convey quantum information
Karol Horodecki, Michal Horodecki, Pawel Horodecki +2
By sending systems in specially prepared quantum states, two parties can communicate without an eavesdropper being able to listen. The technique, called quantum cryptography, enabl…
A decoupling approach to the quantum capacity
Patrick Hayden, Michal Horodecki, Andreas Winter +1
We give a short proof that the coherent information is an achievable rate for the transmission of quantum information through a noisy quantum channel. Our method is to produce rand…
