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…
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…
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…
Theory of integer quantum Hall polaritons in graphene
F. M. D. Pellegrino, L. Chirolli, Rosario Fazio +2
We present a theory of the cavity quantum electrodynamics of the graphene cyclotron resonance. By employing a canonical transformation, we derive an effective Hamiltonian for the s…
Edge channel mixing induced by potential steps in an integer quantum Hall system
D. Venturelli, V. Giovannetti, F. Taddei +4
We investigate the coherent mixing of co-propagating edge channels in a quantum Hall bar produced by step potentials. In the case of two edge channels it is found that, although a…
Electronic implementations of Interaction-Free Measurements
L. Chirolli, E. Strambini, V. Giovannetti +5
Three different implementations of interaction-free measurements (IFMs) in solid-state nanodevices are discussed. The first one is based on a series of concatenated Mach-Zehnder in…
Coherent detection of electron dephasing
E. Strambini, L. Chirolli, V. Giovannetti +4
We show that an Aharonov-Bohm (AB) ring with asymmetric electron injection can act as a coherent detector of electron dephasing. The presence of a dephasing source in one of the tw…
