The estimation of properties of quantum states — such as entanglement — is a core need for the development of quantum technologies, yet remaining a demanding challenge. Standard approaches to property estimation rely on the modeling of the measurement apparatus and, often, a priori assumptions on their working principles. Even small deviations can greatly affect … Continua a leggere
Traditional quantum metrology assesses precision using the figures of merit of continuous-valued parameter estimation. Recently, quantum digital estimation was introduced: it evaluates the performance information theoretically by quantifying the number of significant bits of the parameter, redefining key benchmarks like the Heisenberg bound. Here, we report the first experimental realization of a Quantum Analog-to-Digital Converter … Continua a leggere
Randomness certification is a foundational and practical aspect of quantum information science, essential for securing quantum communication protocols. Traditionally, these protocols have been implemented and validated with a single entanglement source, as in the paradigmatic Bell scenario. However, advancing these protocols to support more complex configurations involving multiple entanglement sources is key to building robust … Continua a leggere
