Information geometric quantification of effective privacy in quantum metrology
Luca Bianchi, Shimpei Yamaguchi, Wojciech Roga +2
The paper introduces an information‑geometric framework to quantify privacy and accessibility in quantum metrology by measuring volumes in the parameter space, and applies it to ex…
A Compressive Sensing Inspired Monte-Carlo Method for Combinatorial Optimization
Baptiste Chevalier, Shimpei Yamaguchi, Wojciech Roga +1
In this paper, we present a Monte-Carlo Compressive Optimization algorithm, a new method to tackle combinatorial optimization problems, including Black-Box or complicated objective…
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…
