Catalytic Enhancement of Coherence in Noisy Quantum Channels and Characterization of Strictly Incoherent Operations
Priyabrata Char, Dipayan Chakraborty, Indrani Chattopadhyay +1
In realistic quantum information processing tasks, quantum states are inevitably affected by environmental noise, leading to decoherence and degradation of useful quantum resources…
Genuinely entangled subspaces beyond strongly nonlocal unextendible biseparable bases
Subrata Bera, Atanu Bhunia, Indranil Biswas +2
Quantum information theory reveals a clear distinction between local and nonlocal correlations through the entanglement across spatially separated subsystems. The orthogonal comple…
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…
