Abstract: The Partial Information Decomposition (PID) takes one step beyond Shannon's theory in decomposing the information two variables $A,B$ possess about a third variable $T$ into distinct parts: unique, shared (or redundant) and synergistic information. Here we show how these concepts can be defined in a quantum setting. We apply a quantum PID to scrambling in quantum many-body systems, for which a quantum-theoretic description has been proven productive. Unique information in particular provides a finer description of scrambling than does the so-called tri-information.

Quantum information scrambling in adiabatically-driven critical systems [49.1574468325115]
Quantum information scrambling refers to the spread of the initially stored information over many degrees of freedom of a quantum many-body system. We extend the notion of quantum information scrambling to critical quantum many-body systems undergoing an adiabatic evolution.

Quantum security and theory of decoherence [0.0]
We investigate how the standard cryptographic assumption of shielded laboratory, stating that data generated by a secure quantum device remain private unless explicitly published, is disturbed by the einselection mechanism of quantum Darwinism. We derive a trade-off relation between eavesdropper's guessing probability $P_guess$ and the collective decoherence factor $Gamma.

We experimentally implement our protocol on a linear optical network and exhibit its effectiveness to accomplish the bipartite entanglement detection for 5-qubit quantum pure states and 2-qubit quantum mixed states.

Modified Relational Quantum Mechanics [0.0]
An observer can develop an internally consistent description of the universe but it will, of necessity, differ in particulars from the description developed by any other observer. The state vector is epistomological and relative to a given quantum system as in the original relational quantum mechanics.

We focus on the coherent static and dynamic disorder to investigate anomalous and classical transport. Our results show that a Quantum Walk can be considered as a readout device of information about defects and perturbations occurring in complex networks.

Genuine Network Multipartite Entanglement [62.997667081978825]
We argue that a source capable of distributing bipartite entanglement can, by itself, generate genuine $k$-partite entangled states for any $k$. We provide analytic and numerical witnesses of genuine network entanglement, and we reinterpret many past quantum experiments as demonstrations of this feature.
