Single Qubit Quantum Secret Sharing
Christian Schmid, Pavel Trojek, Harald Weinfurter +3
We present a simple and practical protocol for the solution of a secure multiparty communication task, the secret sharing, and its experimental realization. In this protocol, a sec…

Experimental quantum communication complexity
Pavel Trojek, Christian Schmid, Mohamed Bourennane +3
We prove that the fidelity of two exemplary communication complexity protocols, allowing for an N-1 bit communication, can be exponentially improved by N-1 (unentangled) qubit comm…
