Quantum speed limit for the creation and decay of quantum correlations
K. G Paulson, Subhashish Banerjee
We derive Margolus-Levitin and Mandelstamm-Tamm type bound on the quantum speed limit time for the creation and decay of quantum correlations by an amount in a quantum system evolv…
Ground state many-body quantum entanglement of frustrated transverse field models on square lattice
Vikas Vijigiri, K G Paulson, Saptarshi Mandal +1
We study the ground state (GS) many-body quantum entanglement of two different transverse field models on a quasi-2D square lattice relevant to a Hydrogen-bonded crystal, i.e, squa…
Tri-partite non-maximally entangled mixed states as a resource for optimum controlled quantum teleportation fidelity
K. G. Paulson, Prasanta K. Panigrahi
Three-qubit mixed states are used as a channel for controlled quantum teleportation (CQT) of single-qubit states. The connection between different channel parameters to achieve max…
Rank dependent bounds on mixedness and entanglement for quantum teleportation
K. G Paulson, S. V. M Satyanarayana
Entanglement and mixedness of a bipartite mixed state resource are crucial for the success of quantum teleportation. Upper bounds on measures of mixedness, namely, von Neumann entr…
