Reversible transformations from pure to mixed states, and the unique measure of information
Michal Horodecki, Pawel Horodecki, Jonathan Oppenheim
Transformations from pure to mixed states are usually associated with information loss and irreversibility. Here, a protocol is demonstrated allowing one to make these transformati…
Mean of continuous variables observable {\it via} measurement on single qubit
Pawel Horodecki
It is shown that mean value of any observable with bounded spectrum can be uniquely determined from binary statistics of the measurement performed on {\it single} qubit ancilla cou…
Information as a resource in distributed quantum systems
Michal Horodecki, Karol Horodecki, Pawel Horodecki +4
A new paradigm for distributed quantum systems where information is a valuable resource is developed. After finding a unique measure for information, we construct a scheme for it's…
Separability of mixed quantum states: linear contractions approach
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki
Recently, a new and powerful separability criterion was introduced in [O. Rudolph, quant-ph/0202121] and [Chen {\it et al.}, quant-ph/0205017]. Composing the main idea behind the a…
Direct estimations of linear and non-linear functionals of a quantum state
Artur K. Ekert, Carolina Moura Alves, Daniel K. L. Oi +3
We present a simple quantum network, based on the controlled-SWAP gate, that can extract certain properties of quantum states without recourse to quantum tomography. It can be used…
