CHSH inequalities with appropriate response function for POVM and their quantum violation
Asmita Kumari, A. K. Pan
In the derivation of local bound of a Bell's inequality, the response functions corresponding to the different outcomes of measurements are fixed by the relevant hidden variables i…
On the violation of Lders bound of macrorealist and noncontextual inequalities
Asmita Kumari, Md. Qutubuddin, A. K. Pan
In a recent Letter [PRL, 113, 050401 (2014)], it is shown that the quantum violation of a three-time Leggett-Garg inequality (LGI) for a dichotomic qutrit system can exceed the L$\…
Faithful Pointer for qubit measurement
Asmita Kumari, A. K. Pan
In the context of von Neumann projective measurement scenario for a qubit system, it is widely believed that the mutual orthogonality between the post-interaction pointer states is…
Sub-Planck structure in a mixed state
Asmita Kumari, A. K. Pan, P. K. Panigrahi
The persistence of sub-Planck structure in phase space with loss of coherence is demonstrated in a mixed state, which comprises two terms in the density matrix. Its utility in carr…
Swapping Intra-photon entanglement to Inter-photon entanglement using linear optical devices
Mohit Lal Bera, Abhishek Ghosh, Asmita Kumari +1
We propose a curious protocol for swapping the intra-photon entanglement between path and polarization degrees of freedom of a single photon to inter-photon entanglement between tw…
