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…
