Depolarizing channel parameter estimation using noisy initial states
David Collins, Jaimie Stephens
We consider estimating the parameter associated with the qubit depolarizing channel when the available initial states that might be employed are mixed. We use quantum Fisher inform…

Entanglement Entropy Near Kondo-Destruction Quantum Critical Points
J. H. Pixley, Tathagata Chowdhury, M. T. Miecnikowski +3
We study the impurity entanglement entropy in quantum impurity models that feature a Kondo-destruction quantum critical point (QCP) arising from a pseudogap in the conduction…
