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…
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…
Novel one-shot inner bounds for unassisted fully quantum channels via rate splitting
Sayantan Chakraborty, Aditya Nema, Pranab Sen
We prove the first non-trivial one-shot inner bounds for sending quantum information over an entanglement unassisted two-sender quantum multiple access channel (QMAC) and an unassi…
