Information Fragility or Robustness Under Quantum Channels
Nicholas Laracuente, Graeme Smith
Quantum states naturally decay under noise. Many earlier works have quantified and demonstrated lower bounds on the decay rate, showing exponential decay in a wide variety of conte…

Entropy Uncertainty Relations and Strong Sub-additivity of Quantum Channels
Li Gao, Marius Junge, Nicholas LaRacuente
We prove an entropic uncertainty relation for two quantum channels, extending the work of Frank and Lieb for quantum measurements. This is obtained via a generalized strong super-a…
