Uncertainty from Heisenberg to today
We explore the different meanings of “quantum uncertainty” contained in Heisenberg's
seminal paper from 1927, and also some of the precise definitions that were developed …

Additivity of entropic uncertainty relations
R Schwonnek - Quantum, 2018 - quantum-journal.org
We consider the uncertainty between two pairs of local projective measurements performed
on a multipartite system. We show that the optimal bound in any linear uncertainty relation …
