-theory of non-commutative Bernoulli Shifts
Sayan Chakraborty, Siegfried Echterhoff, Julian Kranz +1
For a large class of C*-algebras , we calculate the -theory of reduced crossed products of Bernoulli shifts by groups satisfying the Baum--Connes co…
One-shot purity distillation with local noisy operations and one-way classical communication
Sayantan Chakraborty, Aditya Nema, Francesco Buscemi
Local pure states represent a fundamental resource in quantum information theory. In this work we obtain one-shot achievable bounds on the rates for local purity distillation, in t…
Symmetrized non-commutative tori revisited
Sayan Chakraborty
For the flip action of on an -dimensional noncommutative torus using an exact sequence by Natsume, we compute the K-theory groups of $A_θ\rtimes \mathbb{Z}…
Centralised multi link measurement compression with side information
Sayantan Chakraborty, Arun Padakandla, Pranab Sen
We prove new one shot achievability results for measurement compression of quantum instruments with side information at the receiver. Unlike previous one shot results for this prob…
