Certainty relations, mutual entanglement and non-displacable manifolds
Zbigniew Puchała, Łukasz Rudnicki, Krzysztof Chabuda +2
We derive explicit bounds for the average entropy characterizing measurements of a pure quantum state of size in orthogonal bases. Lower bounds lead to novel entropic uncer…
Exploring complete positivity in hierarchy equations of motion
Björn Witt, Łukasz Rudnicki, Yoshitaka Tanimura +1
We derive a purely algebraic framework for the identification of hierarchy equations of motion that induce completely positive dynamics and demonstrate the applicability of our app…
Testing for entanglement with periodic coarse-graining
Daniel S. Tasca, Łukasz Rudnicki, Reuben S. Aspden +3
Continuous variables systems find valuable applications in quantum information processing. To deal with an infinite-dimensional Hilbert space, one in general has to handle large nu…
Uncertainty relations for characteristic functions
Łukasz Rudnicki, Daniel S. Tasca, Stephen P. Walborn
We present the uncertainty relation for the characteristic functions (ChUR) of the quantum mechanical position and momentum probability distributions. This inequality is more gener…
