Flux control of measurement back-action and Leggett-Garg correlations in chiral quantum walks
Paolo Luppi
Gauge-invariant fluxes control interference in chiral continuous-time quantum walks. We investigate how they affect sequential measurements at a single vertex, using a dichotomic o…

Reduced Quantum-Reference-Frame Channels for Open Quantum Systems
Paolo Luppi, Viktoria Kabel, Flaminia Giacomini +1
When reference frames are treated quantum mechanically, the subsystem structure of quantum systems is no longer absolute, but depends on the choice of the quantum reference frame (…

Temporal nonclassicality in continuous-time quantum walks
Paolo Luppi, Claudia Benedetti, Andrea Smirne
We investigate the genuinely quantum features of continuous-time quantum walks by combining a single-time and a multi-time quantifier of nonclassicality. On the one hand, we consid…
