Characterizing pairwise swapping capabilities of dense coding channels
Abhishek Muhuri, Nirman Ganguly, Aditi Sen De +1
We introduce a novel multipartite entanglement-assisted classical communication task, referred to as dense coding swapping, in which legitimate parties collaboratively swap the den…
Absolute Schmidt number: characterization, detection and resource-theoretic quantification
Bivas Mallick, Saheli Mukherjee, Nirman Ganguly +1
The dimensionality of entanglement, quantified by the Schmidt number, is a valuable resource for a wide range of quantum information processing tasks. In this work, we introduce th…
Detection of nonabsolute separability in quantum states and channels through moments
Bivas Mallick, Saheli Mukherjee, Nirman Ganguly +1
In quantum information and computation, the generation of entanglement through unitary gates remains a significant and active area of research. However, there are states termed as…
Network nonlocality breaking channels
Kaushiki Mukherjee, Nirman Ganguly
Network nonlocality, a recently noted form of nonlocality has been shown to have distinctive features, marking a significant departure from the notion of standard Bell nonlocality…
Fidelity of entanglement and quantum entropies: unveiling their relationship in quantum states and channels
Komal Kumar, Bivas Mallick, Tapaswini Patro +1
Entanglement serves as a fundamental resource for various quantum information processing tasks. Fidelity of entanglement (which measures the proximity to a maximally entangled stat…
Higher-dimensional entanglement detection and quantum channel characterization using moments of generalized positive maps
Bivas Mallick, Ananda G. Maity, Nirman Ganguly +1
Higher-dimensional entanglement is a valuable resource for several quantum information processing tasks, and is often characterized by the Schmidt number and specific classes of en…
