AbstractIn a world where Quantum Networks are rapidly becoming a reality, the development of the Quantum Internet is gaining increasing interest. Nevertheless, modern quantum networks are still in the early stages of development and have limited capacity to distribute resources among different users – a constraint that needs to be taken into account. In this work, it aims to investigate these constraints, using a novel setup for implementing Quantum Random Access Codes (QRACs), communication protocols known for their quantum advantage over their classical counterparts and semi‐ device‐independent self‐testing applications. The QRAC states, made for the first time using weak coherent pulses instead of entangled single photons, allow us to experimentally test the encoding and decoding strategy from the resource allocation perspective. Moreover, by emulating a coexistent classical communication, it test the resilience of the implementation in presence of noise. The achieved results represent a significant milestone both for theoretical studies of quantum resource allocation and for the implementation of quantum infrastructures capable of coexisting with regular telecommunication networks.
