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…

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…

Multipartite Monogamy of Entanglement for Three Qubit States

Priyabrata Char, Dipayan Chakraborty, Prabir Kumar Dey +4

The distribution of entanglement in a multiparty system can be described through the principles of monogamy or polygamy. Monogamy is a fundamental characteristic of entanglement th…

Catalytic Transformations in Coherence Theory

Priyabrata Char, Dipayan Chakraborty, Amit Bhar +2

In 2016, A. Winter et al.(Physical Review Letters 116 (12) (2016) 120404) provided an operational meaning to relative entropy of coherence and coherence of formation by introducing…

Monogamy Relations for Multiqubit Systems

Priyabrata Char, Prabir Kumar Dey, Amit Kundu +2

Recently a new class of monogamy relations (actually, exponentially many) was provided by Christopher Eltschka et al. in terms of squared concurrence. Their approach restricted to…

Structure of Resource Theory of Block Coherence

Prabir Kumar Dey, Dipayan Chakraborty, Priyabrata Char +3

Emerging from the superposition principle, the resource theory of coherence plays a crucial role in many information-processing tasks. Recently, a generalization to this resource t…
