A unified approach to Local Quantum Uncertainty and Interferometric Power by Metric Adjusted Skew Information
Paolo Gibilisco, Davide Girolami, Frank Hansen
Local quantum uncertainty and interferometric power have been introduced by Girolami et al. in [1,2] as geometric quantifiers of quantum correlations. The aim of the present paper…
Quantifying the difference between many-body quantum states
Davide Girolami, Fabio Anzà
The quantum state overlap is the textbook measure of the difference between two quantum states. Yet, it is inadequate to compare the complex configurations of many-body systems. Th…
An axiomatic measure of one-way quantum information
Davide Girolami
I introduce an algorithm to detect one-way quantum information between two interacting quantum systems, i.e. the direction and orientation of the information transfer in arbitrary…
Coherence and quantum correlations measure sensitivity to dephasing channels
Benjamin Yadin, Pieter Bogaert, Cristian E. Susa +1
We introduce measures of quantum coherence as the speed of evolution of a system under decoherence. That is, coherence is the ability to estimate a dephasing channel, quantified by…
How difficult is it to prepare a quantum state?
Davide Girolami
Consider a quantum system prepared in an input state. One wants to drive it into a target state. Assuming classical states and operations as free resources, I identify a geometric…
Weaving and neural complexity in symmetric quantum states
Cristian E. Susa, Davide Girolami
We study the behaviour of two different measures of the complexity of multipartite correlation patterns, weaving and neural complexity, for symmetric quantum states. Weaving is the…
