Strong nonlocality with more imaginarity and less entanglement
Subrata Bera, Indranil Biswas, Atanu Bhunia +2
Complex numbers are central to the formulation of quantum mechanics, yet their role as a genuine resource is only beginning to be understood. In this work, we demonstrate that quan…
Dilution of Entanglement: Unveiling Quantum State Discrimination Advantages
Atanu Bhunia, Priyabrata Char, Subrata Bera +3
The states in the three-qubit GHZ SLOCC class can exhibit diverse entanglement patterns, as they may have no entanglement in any reduced subsystems, or show entanglement across one…
Entanglement of Assistance as a measure of multiparty entanglement
Indranil Biswas, Atanu Bhunia, Subrata Bera +2
Quantifying multipartite entanglement poses a significant challenge in quantum information theory, prompting recent advancements in methodologies to assess it. We introduce the not…
Exploring strong locality : Quantum state discrimination regime and beyond
Subrata Bera, Atanu Bhunia, Indranil Biswas +2
Based on the conviction of switching information from locally accessible to locally hidden environs, the concept of hidden nonlocality activation has recently been highlighted by B…
