Virtually Abelian Quantum Walks
Giacomo Mauro D'Ariano, Marco Erba, Paolo Perinotti +1
We introduce quantum walks on Cayley graphs of non-Abelian groups. We focus on the easiest case of virtually Abelian groups, and introduce a technique to reduce the quantum walk to…
Quantum from principles
Giulio Chiribella, Giacomo Mauro D'Ariano, Paolo Perinotti
Quantum theory was discovered in an adventurous way, under the urge to solve puzzles-like the spectrum of the blackbody radiation-that haunted the physics community at the beginnin…
Special Relativity in a Discrete Quantum Universe
Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti
The hypothesis of a discrete fabric of the universe--the "Planck scale"--is always on stage, since it solves mathematical and conceptual problems in the infinitely small. However,…
Quantum Reading of Unitary Optical Devices
Michele Dall'Arno, Alessandro Bisio, Giacomo Mauro D'Ariano
We address the problem of quantum reading of optical memories, namely the retrieving of classical information stored in the optical properties of a media with minimum energy. We pr…
How much a Quantum Measurement is Informative?
Michele Dall'Arno, Giacomo Mauro D'Ariano, Massimiliano F. Sacchi
The informational power of a quantum measurement is the maximum amount of classical information that the measurement can extract from any ensemble of quantum states. We discuss its…
