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…
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…
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…
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…
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…
Engineered Josephson diode effect in kinked Rashba nanochannels
Alfonso Maiellaro, Mattia Trama, Jacopo Settino +3
The superconducting diode effect, reminiscent of the unidirectional charge transport in semiconductor diodes, is characterized by a nonreciprocal, dissipationless flow of Cooper pa…
Hallmarks of non-trivial topology in Josephson junctions based on oxide nanochannels
Alfonso Maiellaro, Jacopo Settino, Claudio Guarcello +2
We investigate the topological properties of a Josephson junction obtained by constraining a two-dimensional electron gas at oxide interface to form a quasi-1D conductor. We reveal…
Ballistic transport through quantum point contacts of multi-orbital oxides
J. Settino, C. A. Perroni, F. Romeo +2
Linear and non-linear transport properties through an atomic-size point contact based on oxides two-dimensional electron gas is examined using the tight-binding method and the $\ma…
Spin-orbital polarization of Majorana edge states in oxides nanowires
J. Settino, F. Forte, C. A. Perroni +3
We investigate a paradigmatic case of topological superconductivity in a one-dimensional nanowire with orbitals and a strong interplay of spin-orbital degrees of freedom due to…
