A finite sufficient set of conditions for catalytic majorization
David Elkouss, Ananda G. Maity, Aditya Nema +1
The majorization relation has found numerous applications in mathematics, quantum information and resource theory, and quantum thermodynamics, where it describes the allowable tran…
One-Shot Non-Catalytic Distributed Purity Distillation
Francesco Buscemi, Sayantan Chakraborty, Rahul Jain +2
Pure states are an important resource in many quantum information processing protocols. However, even making a fixed pure state, say , in the laboratory requires a consi…
Noise is resource-contextual in quantum communication
Aditya Nema, Ananda G. Maity, Sergii Strelchuk +1
Estimating the information transmission capability of a quantum channel remains one of the fundamental problems in quantum information processing. In contrast to classical channels…
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…
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…
High probability decoupling via approximate unitary designs and efficient relative thermalisation
Aditya Nema, Pranab Sen
We prove a new concentration result for non-catalytic decoupling by showing that, for suitably large , applying a unitary chosen uniformly at random from an approximate -desi…
Approximate unitary -designs give rise to quantum channels with super additive classical Holevo capacity
Aditya Nema, Pranab Sen
In a breakthrough, Hastings' showed that there exist quantum channels whose classical capacity is superadditive i.e. more classical information can be transmitted by quantum encodi…
Efficiently estimating average fidelity of a quantum logic gate using few classical random bits
Aditya Nema, Pranab Sen
We give three new algorithms for efficient in-place estimation, without using ancilla qubits, of average fidelity of a quantum logic gate acting on a d-dimensional system using muc…
