Controlling the non-Markovianity of quantum Brownian motion
Guglielmo Pellitteri, Vittorio Giovannetti, Vasco Cavina
We analyze the exact dynamics of a generalized quantum Brownian motion model, employing Gaussian master equation methods. We demonstrate that, by modulating the relative weights of…
Quantum capacity analysis of finite-dimensional lossy channels
Sofia Cocciaretto, Vittorio Giovannetti
Traditionally, Quantum Information, and Quantum Communication specifically, have been focused on qubit-based architectures. Recent results, however, highlighted that higher dimensi…
Global control via quantum actuators
Roberto Menta, Francesco Cioni, Riccardo Aiudi +2
We introduce the concept of quantum actuators as mediators for globally controlled quantum computation. Auxiliary quantum systems act as controllable elements that transiently stor…
Exact quantum transport in non-Markovian open Gaussian systems
Guglielmo Pellitteri, Vittorio Giovannetti, Vasco Cavina
We build an exact framework to evaluate heat, energy, and particle transport between Gaussian reservoirs mediated by a quadratic quantum system. By combining full counting statisti…
Quantum Channels on Graphs: a Resonant Tunneling Perspective
Giuseppe Catalano, Farzad Kianvash, Vittorio Giovannetti
Quantum transport on structured networks is strongly influenced by interference effects, which can dramatically modify how information propagates through a system. We develop a qua…
