Genuine Multipartite Nonlocality sharing under sequential measurement
Sk Sahadat Hossain, Indrani Chattopadhyay
The study of quantum nonlocality sharing has garnered significant attention, particularly for two-qubit and three-qubit entangled systems. In this paper, we extend the investigatio…
Pure State Transformations under Block Coherence
Dipayan Chakraborty, Priyabrata Char, Indrani Chattopadhyay +1
Block coherence provides a natural generalization of standard quantum coherence by treating superpositions across different subspaces as a resource. This work studies deterministic…
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…
Entanglement concentration via measurement:- role of imaginarity
Indranil Biswas, Subrata Bera, Ujjwal Sen +2
The role of complex numbers in quantum theory extends beyond mathematical convenience, having recently been formalized as a resource under the framework of the resource theory of i…
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…
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…
