Variational quantum metrology represents a powerful tool for optimizing estimation strategies, resulting in particularly beneficial for multiparameter estimation problems, that often suffer from limitations due to the curse of dimensionality and computational complexity. To overcome these challenges, we develop a variational approach able to efficiently optimize a quantum multiphase sensor. Leveraging the reconfigurability of an … Continua a leggere

Quantum Cellular Automaton (QCA) is a model for universal quantum computation and a natural candidate for digital quantum simulation of relativistic quantum fields. Here we introduce the first photonic platform for implementing QCA-simulation of a free relativistic Dirac quantum field in 1+1 dimension, through a Dirac Quantum Cellular Automaton (DQCA). Encoding the field position degree … Continua a leggere

The 11 February is the ‘International Day of Women and Girls in Science’, a day dedicated to the role of women scientists. The purpose of this initiative is to raise awareness about the gender inequalities in the free access of women and girls to research. The girls and women scientists of Quantum Lab celebrated the … Continua a leggere

Single-photon sources based on semiconductor quantum dots find several applications in quantum information processing due to their high single-photon indistinguishability, on-demand generation, and low multiphoton emission. In this context, the generation of entangled photons represents a challenging task with a possible solution relying on the interference in probabilistic gates of identical photons emitted at different … Continua a leggere

With a kick-off meeting hosted at the Sapienza University of Rome Rectorate, the EPIQUE challenge began today! The research project, funded with 10,340,000 euros by the European Commission, is led by Sapienza University of Rome and coordinated by Fabio Sciarrino and involving 18 partners from 12 different countries… Read the Press Release:

A European €10 million project led by the Sapienza University of Rome with 18 partners (01/17/24) – To pave the way for a European quantum computer based on photons, the quanta of light: this is the challenge of EPIQUE, the research project funded with €10,340,000 by the European Commission and carried out by 18 partners … Continua a leggere

Un gruppo di ricerca internazionale ha ideato e dimostrato che è possibile effettuare calcoli da remoto su processori quantistici mantenendo intatta la privacy di tutti gli utenti coinvolti. I risultati dell’esperimento, condotto presso il Quantum Lab dell’Università Sapienza di Roma, sono stati pubblicati sulla rivista Nature Communications e costituiscono un passo in avanti fondamentale verso … Continua a leggere

Universal blind quantum computing allows users with minimal quantum resources to delegate a quantum computation to a remote quantum server, while keeping intrinsically hidden input, algorithm, and outcome. State-of-art experimental demonstrations of such a protocol have only involved one client. However, an increasing number of multi-party algorithms, e.g. federated machine learning, require the collaboration of … Continua a leggere
