Universal, unambiguous concentration and distillation of Bell pairs
Orsolya Kálmán, Aurél Gábris, Igor Jex +1
The ability of preparing perfect Bell pairs with a practical scheme is of great relevance for quantum communication as well as distributed quantum computing. We propose a scheme wh…

Robustness of chaotic behavior in iterated quantum protocols
Attila Portik, Orosolya Kálmán, Igor Jex +1
One of the simplest possible quantum circuits, consisting of a CNOT gate, a Hadamard gate and a measurement on one of the outputs is known to lead to chaotic dynamics when applied…
