Extreme Quantum Cognition Machines for Deliberative Decision Making
Francesco Romeo, Jacopo Settino
We introduce Extreme Quantum Cognition Machines, a class of quantum learning architectures for deliberative decision making that is tolerant to noisy and contradictory training dat…
Spin Hall and Edelstein effects in a ballistic quantum dot with Rashba spin-orbit coupling
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +11
We study spin-resolved transport in a ballistic quantum dot with Rashba spin-orbit coupling, focusing on charge-to-spin conversion and spin Hall effect. In the regime where the dot…
Theory of charge-to-spin conversion under quantum confinement
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +6
The interplay between spin and charge degrees of freedom in low-dimensional systems is a cornerstone of modern spintronics, where achieving all-electrical control of spin currents…
Topology-Enhanced Superconducting Qubit Networks for In-Sensor Quantum Information Processing
J. Settino, G. G. Luciano, A. Di Bartolomeo +4
We investigate the influence of topology on the magnetic response of inductively coupled superconducting flux-qubit networks. Using exact diagonalization methods and linear respons…
Probing graph topology from local quantum measurements
F. Romeo, J. Settino
We show that global properties of an unknown quantum network, such as the average degree, hub density, and the number of closed paths of fixed length, can be inferred from strictly…
Probing Topological Superconductivity of oxide nanojunctions using fractional Shapiro steps
Claudio Guarcello, Alfonso Maiellaro, Jacopo Settino +4
We theoretically discuss the emergence of fractional Shapiro steps in a Josephson junction created by confining a two-dimensional electron gas at an oxide interface. This phenomeno…
