This research proposes a sequential state-discrimination scheme using weak measurements to allow multiple parties to share quantum uncertainty from a single system. By leveraging maximum-confidence measurements, the study aims to clarify the fundamental limits of sequential information extraction and advance protocols for quantum resource sharing in cryptography and randomness generation. The work provides a theoretical framework for optimizing how non-orthogonal quantum states are utilized across distributed networks.
Sharing quantum indistinguishability with multiple parties
arXiv:2512.15199v3 Announce Type: replace Abstract: Quantum indistinguishability of non-orthogonal quantum states is a valuable resource in quantum information applications such as cryptography and randomness generation. In this article, we present a sequential state-discrimination scheme that enables multiple parties to share quantum uncertainty, in terms of the max relative entropy, generated by a single party. Our scheme is based upon maximum-confidence measurements and takes advantages of weak measurements to allow a number of parties to perform state discrimination on a single quantum system. We review known sequential state discrimination and show how our scheme would work through a number of examples where ensembles may or may not contain symmetries. Our results will have a role to play in understanding the ultimate limits of sequential information extraction and guide the development of quantum resource sharing in sequential settings.
