Scientific activity
Beatrice Polacchi obtained her Ph.D. title in May 2024 at the Quantum Lab with a thesis entitled “Quantum networks on a hybrid photonic platform” jointly with the title of Doctor Europaeus. 
In her Ph.D. thesis, she investigated software and hardware building blocks for hybrid photonic quantum networks. From the software point of view, her thesis explores quantum foundations for the device-independent certification of quantum networks. In this direction, she contributed to the first experimental demonstration of quantum effects in a scenario where standard techniques based on Bell tests would fail. As a second result, she contributed to developing a machine learning-based tool for the certification of arbitrarily large and complex quantum networks. As a third result, she contributed to the proposal of a versatile and scalable multi-client blind quantum computing protocol and provided the first experimental demonstration of a two-client blind quantum computing protocol, in collaboration with Sorbonne University of Paris and Veriqloud. From the hardware point of view, her thesis explores hybrid photonic platforms based on quantum dot single photon sources. In this direction, she contributed to designing a modular plug-in optical platform for the generation of entangled quantum states tailored to single-photon sources. As a second result, she contributed to the investigation of a resonantly driven quantum dot photon source to provide the first experimental quantum teleportation of a genuine vacuum–one-photon qubit.

Beatrice’s current research activities focus on experimental demonstrations of blind quantum computing protocols over different quantum network architectures. Moreover, she investigates quantum dot single-photon sources interfaced with integrated platforms and possible applications of the photon-number encoding for quantum information protocols.She presented her scientific work at national and international scientific conferences. She is a co-author of 6 articles in peer-reviewed scientific journals, including 1 in Nature Communications as the first author, with an h-index of 2 according to Scopus (4 according to Google Scholar).
