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…

Spreading Nonlocality in Quantum Network
Ratul Banerjee, Srijon Ghosh, Shiladitya Mal +1
Starting from several copies of bipartite noisy entangled states, we design a global and optimal local measurement-based protocol in one- and two-dimensional lattices by which any…

Enhancement in performance of quantum battery by ordered and disordered interactions
Srijon Ghosh, Titas Chanda, Aditi Sen De
Considering ground state of a quantum spin model as the initial state of the quantum battery, we show that both ordered and disordered interaction strengths play a crucial role to…
