Coherent edge mixing and interferometry in quantum Hall bilayers
Stefano Roddaro, Luca Chirolli, Fabio Taddei +2
We discuss the implementation of a beam splitter for electron waves in a quantum Hall bilayer. Our architecture exploits inter-layer tunneling to mix edge states belonging to diffe…
Selective writing and read-out of a register of static qubits
A. De Pasquale, F. Ciccarello, K. Yuasa +1
We propose a setup comprising an arbitrarily large array of static qubits (SQs), which interact with a flying qubit (FQ). The SQs work as a quantum register, which can be written o…
Thermodynamics of discrete quantum processes
Janet Anders, Vittorio Giovannetti
We define thermodynamic configurations and identify two primitives of discrete quantum processes between configurations for which heat and work can be defined in a natural way. Thi…
Electromagnetic channel capacity for practical purposes
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone +1
We give analytic upper bounds to the channel capacity C for transmission of classical information in electromagnetic channels (bosonic channels with thermal noise). In the practica…
Ergodic and Mixing Quantum Channels in Finite Dimensions
Daniel Burgarth, Giulio Chiribella, Vittorio Giovannetti +2
The paper provides a systematic characterization of quantum ergodic and mixing channels in finite dimensions and a discussion of their structural properties. In particular, we disc…
Minimal Self-Contained Quantum Refrigeration Machine Based on Four Quantum Dots
Davide Venturelli, Rosario Fazio, Vittorio Giovannetti
We present a theoretical study of an electronic quantum refrigerator based on four quantum dots arranged in a square configuration, in contact with as many thermal reservoirs. We s…
