Self-testing quantum states via nonmaximal violation in Hardy's test of nonlocality
Ashutosh Rai, Matej Pivoluska, Souradeep Sasmal +3
Self-testing protocols enable certification of quantum devices without demanding full knowledge about their inner workings. A typical approach in designing such protocols is based…
Certifying beyond quantumness of locally quantum no-signalling theories through quantum input Bell test
Edwin Peter Lobo, Sahil Gopalkrishna Naik, Samrat Sen +3
Physical theories constrained with local quantum structure and satisfying the no-signalling principle can allow beyond-quantum global states. In a standard Bell experiment, correla…
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…
Local Quantum State Marking
Samrat Sen, Edwin Peter Lobo, Sahil Gopalkrishna Naik +8
We propose the task of local state marking (LSM), where some multipartite quantum states chosen randomly from a known set of states are distributed among spatially separated partie…
Composition of multipartite quantum systems: perspective from time-like paradigm
Sahil Gopalkrishna Naik, Edwin Peter Lobo, Samrat Sen +5
Figuring out the physical rationale behind natural selection of quantum theory is one of the most acclaimed quests in quantum foundational research. This pursuit has inspired sever…
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…
