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…
Information transmission over an amplitude damping channel with an arbitrary degree of memory
A. D'Arrigo, G. Benenti, G. Falci +1
We study the performance of a partially correlated amplitude damping channel acting on two qubits. We derive lower bounds for the single-shot classical capacity by studying two kin…
Detecting lower bounds to quantum channel capacities
Chiara Macchiavello, Massimiliano F. Sacchi
We propose a method to detect lower bounds to quantum capacities of a noisy quantum communication channel by means of few measurements. The method is easily implementable and does…
Quantum conditional operations
Alessandro Bisio, Michele Dall'Arno, Paolo Perinotti
An essential element of classical computation is the "if-then" construct, that accepts a control bit and an arbitrary gate, and provides conditional execution of the gate depending…
Violation of Bell inequalities in larger Hilbert spaces: robustness and challenges
Werner Weiss, Giuliano Benenti, Giulio Casati +4
We explore the challenges posed by the violation of Bell-like inequalities by -dimensional systems exposed to imperfect state-preparation and measurement settings. We address, i…
Cooperative shielding in many-body systems with long-range interaction
Lea F. Santos, Fausto Borgonovi, Giuseppe Luca Celardo
In recent experiments with ion traps, long-range interactions were associated with the exceptionally fast propagation of perturbation, while in some theoretical works they have als…
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…
Efficient superdense coding in the presence of non-Markovian noise
Bi-Heng Liu, Xiao-Min Hu, Yun-Feng Huang +7
Many quantum information tasks rely on entanglement, which is used as a resource, for example, to enable efficient and secure communication. Typically, noise, accompanied by loss o…
Quantum Time
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
We give a consistent quantum description of time, based on Page and Wootters' conditional probabilities mechanism, that overcomes the criticisms that were raised against similar pr…
Experimental generation of entanglement from classical correlations via non-unital local noise
Adeline Orieux, Mario A. Ciampini, Paolo Mataloni +3
We experimentally show how classical correlations can be turned into quantum entanglement, via the presence of non-unital local noise and the action of a CNOT gate. We first implem…
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…
The time as an emergent property of quantum mechanics, a synthetic description of a first experimental approach
E Moreva, G Brida, M Gramegna +3
The "problem of time" in present physics substantially consists in the fact that a straightforward quantization of the general relativistic evolution equation and constraints gener…
