-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…
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…
One-shot inner bounds for sending private classical information over a quantum MAC
Sayantan Chakraborty, Aditya Nema, Pranab Sen
We provide the first inner bounds for sending private classical information over a quantum multiple access channel. We do so by using three powerful information theoretic technique…
One-shot multi-sender decoupling and simultaneous decoding for the quantum MAC
Sayantan Chakraborty, Aditya Nema, Pranab Sen
In this work, we prove a novel one-shot multi-sender decoupling theorem generalising Dupuis result. We start off with a multipartite quantum state, say on A1 A2 R, where A1, A2 are…
Tracing projective modules over noncommutative orbifolds
Sayan Chakraborty
For an action of a finite cyclic group on an -dimensional noncommutative torus we give sufficient conditions when the fundamental projective modules over , which…
Improved Bounds for Perfect Sampling of -Colorings in Graphs
Siddharth Bhandari, Sayantan Chakraborty
We present a randomized algorithm that takes as input an undirected -vertex graph with maximum degree and an integer , and returns a random proper -coloring o…
