Quantum memristors represent a promising interface between quantum and neuromorphic computing, combining the nonlinear, memory-dependent behavior of classical memristors with the properties of quantum states. An optical quantum memristor can be realized with a vacuum–one-photon qubit entering a tunable beam splitter whose reflectivity is adapted according to the mean number of photons in the device. … Continua a leggere
The POQUB project, “PhOtonics QUantum Bernoulli Factory,” led by Fabio Sciarrino as Principal Investigator, started on 1 March 2025.POQUB is hosted by Quantum Lab, Department of Physics – Sapienza (https://www.quantumlab.it/), and will also involve the National Quantum Science and Technology Institute (NQSTI) (https://nqsti.it/) for the activities of technology transfer and for the interactions with the … Continua a leggere
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
Venerdì 21 Febbraio Fabio Sciarrino interverrà presso il dipartimento di Fisica dell’Università di Catania, all’evento di Tecnologie Quantistiche, che ha l’obiettivo di proporre percorsi di innovazione sulle nuove Tecnologie Quantistiche presso il mondo imprenditoriale, dalle grandi aziende.
The implementation of large-scale universal quantum computation represents a challenging and ambitious task on the road to quantum processing of information. In recent years, an intermediate approach has been pursued to demonstrate quantum computational advantage via non-universal computational models. A relevant example for photonic platforms has been provided by the Boson Sampling paradigm and its … Continua a leggere
