From no causal loop to absoluteness of cause: discarding the quantum NOT logic

Anandamay Das Bhowmik, Preeti Parashar, Guruprasad Kar +1

The principle of `absoluteness of cause' (AC) assumes the cause-effect relation to be observer independent and is a distinct assertion than prohibiting occurrence of any causal loo…

Better transmission with lower capacity: lossy compression over quantum channels

Sristy Agrawal, Rajashik Tarafder, Graeme Smith +2

Shannon's channel coding theorem describes the maximum possible rate of reliable information transfer through a classical noisy communication channel. It, together with the source…

Mutually Unbiased Balanced Functions & Generalized Random Access Codes

Vaisakh M, Ram krishna Patra, Mukta Janpandit +3

Quantum resources and protocols are known to outperform their classical counterparts in variety of communication and information processing tasks. Random Access Codes (RACs) are on…

On the state space structure of tripartite quantum systems

Hari Krishnan S, Ashish Ranjan, Manik Banik

State space structure of tripartite quantum systems is analyzed. In particular, it has been shown that the set of states separable across all the three bipartitions [say $\mathcal{…

Device-independent bounds from Cabello's nonlocality argument

Ashutosh Rai, Matej Pivoluska, Martin Plesch +3

Hardy-type arguments manifest Bell nonlocality in one of the simplest possible ways. Except for demonstrating nonclassical signature of entangled states in question, they can also…

Random-Receiver Quantum Communication

Some Sankar Bhattacharya, Ananda G. Maity, Tamal Guha +2

We introduce the task of random-receiver quantum communication, in which a sender transmits a quantum message to a receiver chosen from a list of n spatially separated parties. The…
