Precanonical quantization and the Schrödinger wave functional revisited
I. V. Kanatchikov
We address the issue of the relation between the canonical functional Schrödinger representation in quantum field theory and the approach of precanonical field quantization propose…
The Resource Theory of Quantum States Out of Thermal Equilibrium
Fernando G. S. L. Brandão, Michał Horodecki, Jonathan Oppenheim +2
The ideas of thermodynamics have proved fruitful in the setting of quantum information theory, in particular the notion that when the allowed transformations of a system are restri…
No-broadcasting of non-signalling boxes via operations which transform local boxes into local ones
P. Joshi, A. Grudka, K. Horodecki +3
We deal with families of probability distributions satisfying non-signalling condition, called non-signalling boxes and consider class of operations that transform local boxes into…
Schemes of transmission of classical information via quantum channels with many senders: discrete and continuous variables cases
L. Czekaj, J. K. Korbicz, R. W. Chhajlany +1
Superadditivity effects in the classical capacity of discrete multi-access channels (MACs) and continuous variable (CV) Gaussian MACs are analysed. New examples of the manifestatio…
Distillation of entanglement by projection on permutationally invariant subspaces
Mikołaj Czechlewski, Andrzej Grudka, Michał Horodecki +2
We consider distillation of entanglement from two qubit states which are mixtures of three mutually orthogonal states: two pure entangled states and one pure product state. We dist…
Convergence to equilibrium under a random Hamiltonian
Fernando G. S. L. Brandão, Piotr Ćwikliński, Michał Horodecki +3
We analyze equilibration times of subsystems of a larger system under a random total Hamiltonian, in which the basis of the Hamiltonian is drawn from the Haar measure. We obtain th…
Directed percolation effects emerging from superadditivity of quantum networks
L. Czekaj, R. W. Chhajlany, P. Horodecki
Entanglement indcued non--additivity of classical communication capacity in networks consisting of quantum channels is considered. Communication lattices consisiting of butterfly-t…
Collective Uncertainty Entanglement Test
Łukasz Rudnicki, Paweł Horodecki, Karol Życzkowski
For a given pure state of a composite quantum system we analyze the product of its projections onto a set of locally orthogonal separable pure states. We derive a bound for this pr…
Characterizing quantumness via entanglement creation
Sevag Gharibian, Marco Piani, Gerardo Adesso +2
In [M. Piani et al., arXiv:1103.4032 (2011)] an activation protocol was introduced which maps the general non-classical (multipartite) correlations between given systems into bipar…
All non-classical correlations can be activated into distillable entanglement
Marco Piani, Sevag Gharibian, Gerardo Adesso +3
We devise a protocol in which general non-classical multipartite correlations produce a physically relevant effect, leading to the creation of bipartite entanglement. In particular…
Subadditivity of the minimum output entropy and superactivation of the classical capacity of quantum multiple access channels
Lukasz Czekaj
We study subadditivity of the minimum output entropy () of quantum multiple access channels (MACs). We provide an example of violation of the additivity theorem for $H_{mi…
