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…
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…
Fault-tolerant modular quantum computing with surface codes using single-shot emission-based hardware
Siddhant Singh, Rikiya Kashiwagi, Kazufumi Tanji +4
Fault-tolerant modular quantum computing requires stabilizer measurements across the modules in a quantum network. For this, entangled states of high quality and rate must be distr…
