Activation of thermal states by coherently controlled thermalization processes
Kyrylo Simonov, Saptarshi Roy, Tamal Guha +2
Thermalization processes degrade the states of any working medium, turning any initial state into a passive state from which no work can be extracted. Recently, it has been shown t…
Quantum networks boosted by entanglement with a control system
Tamal Guha, Saptarshi Roy, Giulio Chiribella
Networks of quantum devices with coherent control over their configuration offer promising advantages in quantum information processing. So far, the investigation of these advantag…
Bipartite polygon models: entanglement classes and their nonlocal behaviour
Mayalakshmi Kolangatt, Thigazholi Muruganandan, Sahil Gopalkrishna Naik +3
Hardy's argument constitutes an elegantly logical test for identifying nonlocal features of multipartite correlations. In this paper, we investigate Hardy's nonlocal behavior withi…
Genuine Activation of Quantum Nonlocality: Stronger Than Local Indistinguishability
Tathagata Gupta, Subhendu B. Ghosh, Ardra A +5
The structure of quantum theory assures the discrimination of any possible orthogonal set of states. However, the scenario becomes highly nontrivial in the limited measurement sett…
Classical analogue of quantum superdense coding and communication advantage of a single quantum system
Ram Krishna Patra, Sahil Gopalkrishna Naik, Edwin Peter Lobo +5
We analyze utility of communication channels in absence of any short of quantum or classical correlation shared between the sender and the receiver. To this aim, we propose a class…
Activating Strongest Possible Nonlocality from Local Sets: An Elimination Paradigm
Subhendu B. Ghosh, Tathagata Gupta, Ardra A. V. +4
Apart from the Bell nonlocality, which deals with the correlations generated from the local input-output statistics, quantum theory exhibits another kind of nonlocality that involv…
