Improving the Loss Tolerance of Heralded Photonic GHZ States for Long-Distance Device-Independent Conference Key Agreement
Yazeed K. Alwehaibi, Makoto Ishihara, Shakib Daryanoosh +6
Heralded multipartite entanglement distribution is a key requirement for device-independent conference key agreement (DI-CKA) over lossy quantum networks. Although locally equivale…
Symmetry-resolved tree tensor network analysis of Bell-state discrimination with ancilla-assisted passive linear optics
Anand Kumar, Wojciech Roga, Devendra Kumar Mishra +1
Ancillary photons allow passive linear-optical Bell-state discrimination to exceed the one-half probability of success limit achievable with vacuum auxiliary modes. For a fixed ana…
Enhancing noise robustness in device-independent conference key agreement with asymmetric parity-CHSH inequalities
Makoto Ishihara, Wojciech Roga, Jonatan Bohr Brask +1
Conference key agreement allows multiple remote parties to establish a shared secret key with information-theoretical security. In device-independent conference key agreement, secu…
Information geometric quantification of effective privacy in quantum metrology
Luca Bianchi, Shimpei Yamaguchi, Wojciech Roga +2
Privacy of a quantum metrological protocol concerns the extent to which single parameters can be kept inaccessible to an observer or to other users of the network. In this work, an…
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…
