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…
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…
A nonparametric approach to assess undergraduate performance
Hildete P. Pinheiro, Pranab K. Sen, Aluísio Pinheiro +1
Nonparametric methodologies are proposed to assess college students' performance. Emphasis is given to gender and sector of High School. The application concerns the University of…
