Unifying classical and quantum key distillation
Matthias Christandl, Artur Ekert, Michal Horodecki +3
Assume that two distant parties, Alice and Bob, as well as an adversary, Eve, have access to (quantum) systems prepared jointly according to a tripartite state. In addition, Alice…
Quantum key distribution based on private states: unconditional security over untrusted channels with zero quantum capacity
Karol Horodecki, Michal Horodecki, Pawel Horodecki +2
We prove unconditional security for a quantum key distribution (QKD) protocol based on distilling pbits (twisted ebits) [quant-ph/0309110] from an arbitrary untrusted state that is…
Multiple scattering and electron-uracil collisions at low energies
Sergey Yalunin, Sergey B. Leble
Links between two well known methods: methods of zero-range and non-overlapped (muffin-tin) potentials are discussed. Some difficulties of the method of zero-range potentials and i…
Universal observable detecting all two-qubit entanglement and determinant based separability tests
Remigiusz Augusiak, Maciej Demianowicz, Pawel Horodecki
We construct a single observable measurement of which mean value on four copies of an {\it unknown} two-qubit state is sufficient for unambiguous decision whether the state is sepa…
Quantum channel capacities - multiparty communication
Maciej Demianowicz, Pawel Horodecki
We analyze different aspects of multiparty communication over quantum memoryless channels and generalize some of key results known from bipartite channels to that of multiparty sce…
Aspects of multistation quantum information broadcasting
Maciej Demianowicz, Paweł Horodecki
We study quantum information transmission over multiparty quantum channel. In particular, we show an equivalence of different capacity notions and provide a multiletter characteriz…
General construction of noiseless networks detecting entanglement with help of linear maps
P. Horodecki, R. Augusiak, M. Demianowicz
We present the general scheme for construction of noiseless networks detecting entanglement with the help of linear, hermiticity-preserving maps. We show how to apply the method to…
Quantum states representing perfectly secure bits are always distillable
Pawel Horodecki, Remigiusz Augusiak
It is proven that recently introduced states with perfectly secure bits of cryptographic key (private states representing secure bit) [K. Horodecki et al., Phys. Rev. Lett. 94, 160…
