Are quantum correlations symmetric ?
Karol Horodecki, Michal Horodecki, Pawel Horodecki
To our knowledge, all known bipartite entanglement measures are symmetric under exchange of subsystems. We ask if an entanglement measure that is not symmetric can exist. A related…
Direct measurement of non-linear properties of bipartite quantum states
Fabio Antonio Bovino, Giuseppe Castagnoli, Artur Ekert +3
Non-linear properties of quantum states, such as entropy or entanglement, quantify important physical resources and are frequently used in quantum information science. They are usu…
Low dimensional bound entanglement with one-way distillable cryptographic key
Karol Horodecki, Lukasz Pankowski, Michal Horodecki +1
We provide a class of bound entangled states that have positive distillable secure key rate. The smallest state of this kind is , which shows that peculiar security co…
General paradigm for distilling classical key from quantum states
Karol Horodecki, Michal Horodecki, Pawel Horodecki +1
We develop a formalism for distilling a classical key from a quantum state in a systematic way, expanding on our previous work on secure key from bound entanglement [K. Horodecki e…
Quantumness of ensemble from no-broadcasting principle
M. Horodecki, P. Horodecki, R. Horodecki +1
Quantum information, though not precisely defined, is a fundamental concept of quantum information theory which predicts many fascinating phenomena and provides new physical resour…
On quantum non-signalling boxes
M. Piani, M. Horodecki, P. Horodecki +1
A classical non-signalling (or causal) box is an operation on classical bipartite input with classical bipartite output such that no signal can be sent from a party to the other th…
