Private quantum network sensing with efficient multi-partite entanglement distribution via lossy channels

Yoshihiro Ueda, Makoto Ishihara, Wojciech Roga +1

Quantum network sensing shows potential to enhance the estimation precision for functions of spatially distributed parameters beyond the shot noise limit. The key resource required…

Friendship paradox disappears under degree biased network sampling

Wojciech Roga

We show that in an undirected graph under degree biased sampling the expected degree of vertices is equal to the expected degree of their neighbors. In consequence, under the biase…

Multipartite device-independent quantum key distribution using W states

Makoto Ishihara, Wojciech Roga, Masahiro Takeoka

Multipartite device-independent quantum key distribution (DI-QKD), also known as device-independent conference key agreement, enables more than two remote parties to share a common…

Demonstration of sequential processors with quantum advantage and analysis of classical performance limits

Shota Tateishi, Wenhao Wang, Baptiste Chevalier +3

In this paper, we theoretically and experimentally analyze sequential processors with limited communication between parts. We compare the expressivity of sequential quantum and cla…
