Revealing hidden nonlocality and preparation contextuality for an arbitrary input Bell inequality
Asmita Kumari, Saikat Patra
In recent years, the activation of hidden nonlocality for a mixed entangled state, admitting a local model, has gained considerable interest. In this paper, we study the activation…
Sharing preparation contextuality in Bell experiment by arbitrary pair of sequential observers
Asmita Kumari, Alok Kumar Pan
Based on the quantum violation of bipartite Bell inequality, it has been demonstrated that the sharing of non-locality can be demonstrated for at most two sequential observers at o…
Activation of hidden nonlocality using local filtering operations based on CGLMP inequality
Asmita Kumari
Entanglement is necessary but not sufficient to demonstrate nonlocality as there exist local entangled states which do not violate any Bell inequality. In recent years, the activat…
Generalised quantum speed limit for arbitrary time-continuous evolution
Dimpi Thakuria, Abhay Srivastav, Brij Mohan +2
The quantum speed limit describes how quickly a quantum system can evolve in time from an initial state to a final state under a given dynamics. Here, we derive a generalised quant…
Local PT-symmetric evolutions on separable states and violation of no-signaling
Asmita Kumari, Ujjwal Sen
We show that local PT-symmetric evolutions can lead to violation of the no-signaling principle for separable and even classically correlated bipartite shared quantum states. For cl…
Lüders bounds of Leggett-Garg inequalities, - symmetric evolution and arrow-of-time
Asmita Kumari, A. K. Pan
Leggett Garg inequalities (LGIs) test the incompatibility between the notion of macrorealism and quantum mechanics. For unitary dynamics, the optimal quantum violation of an LGI is…
