Multipartite Entanglement Accumulation in Quantum States: Localizable Generalized Geometric Measure
Debasis Sadhukhan, Sudipto Singha Roy, Amit Kumar Pal +3
Multiparty quantum states are useful for a variety of quantum information and computation protocols. We define a multiparty entanglement measure based on local measurements on a mu…
Reducing Computational Complexity of Quantum Correlations
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We address the issue of reducing the resource required to compute information-theoretic quantum correlation measures like quantum discord and quantum work deficit in two qubits and…
Enhancement of Quantum Correlation Length in Quenched Disordered Spin Chains
Debasis Sadhukhan, Sudipto Singha Roy, Debraj Rakshit +3
Classical correlations of ground states typically decay exponentially and polynomially, respectively for gapped and gapless short-ranged quantum spin systems. In such systems, enta…
