Decoherence-free mechanism to protect long-range entanglement against decoherence
Leela Ganesh Chandra Lakkaraju, Srijon Ghosh, Aditi Sen De
Quantum spin models with variable-range interactions can exhibit certain quantum characteristics that a short-ranged model cannot possess. By considering the quantum XYZ model whos…
Robustness of Higher Dimensional Nonlocality against dual noise and sequential measurements
Saptarshi Roy, Asmita Kumari, Shiladitya Mal +1
Robustness in the violation of Collins-Linden-Gisin-Masser-Popescu (CGLMP) inequality is investigated from the dual perspective of noise in measurements as well as in states. To qu…
Three qubits in less than three baths: Beyond two-body system-bath interactions in quantum refrigerators
Ahana Ghoshal, Sreetama Das, Amit Kumar Pal +2
We show that quantum absorption refrigerators, which have traditionally been studied as of three qubits, each of which is connected to a thermal reservoir, can also be constructed…
Gain in Performance of Teleportation with Uniformity-breaking Distributions
Saptarshi Roy, Shiladitya Mal, Aditi Sen De
Prior information about the input state can be utilized to enhance the efficiency of quantum teleportation which we quantify using the first two moments of fidelity. The input know…
Unifying Two Notions of Nonlocality in Quantum Theory
Shiladitya Mal, Aditi Sen De
Ensembles containing orthogonal product states are found to be indistinguishable under local operations and classical communication (LOCC), thereby showing irreversibility in the p…
Restrictions on shareability of classical correlations for random multipartite quantum states
Saptarshi Roy, Shiladitya Mal, Aditi Sen De
Unlike quantum correlations, the shareability of classical correlations (CCs) between two-parties of a multipartite state is assumed to be free since there exist states for which C…
