Fundamental limits of parameter estimation with heralded optical non-Gaussian states generated from Gaussian resources
Shohei Kiryu, Kazufumi Tanji, Yoshihiro Ueda +2
Non-Gaussian states can exhibit large quantum Fisher information (QFI) in quantum sensing. In optical systems, however, its generation is often probabilistic via the boson-sampling…
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…
Linear-optical generation of hybrid GKP entanglement from small-amplitude cat states
Shohei Kiryu, Yohji Chin, Masahiro Takeoka +1
Hybrid bosonic codes combining bosonic codes with photon states offer a promising pathway for fault-tolerant quantum computation. However, the efficient generation of such states i…
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…
