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 quantum imaginarity using moments and its interferometric realization
Sudip Chakrabarty, Saheli Mukherjee, Ananda G. Maity +1
Complex numbers, intrinsic to the formulation of quantum theory, play a pivotal role in enabling advantages across a broad range of quantum information-processing tasks. Despite th…
Probing Kirkwood-Dirac nonpositivity and its operational implications via moments
Sudip Chakrabarty, Bivas Mallick, Saheli Mukherjee +1
The Kirkwood-Dirac (KD) distribution has recently emerged as a powerful quasiprobability framework with wide-ranging applications in quantum information processing tasks. In this w…
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…
Classifying Measurement Incompatibility under Classical Pre- and Post-Processing Operations
Arun Kumar Das, Saheli Mukherjee, Debashis Saha +2
Measurement incompatibility has proved to be an important resource for quantum information processing. In this work, we present an operational approach that leverages classical ope…
Certifying the dimensionality of any quantum channel with minimal assumptions
Saheli Mukherjee, Bivas Mallick, Pratik Ghosal
High-dimensional entanglement offers significant advantages over its low-dimensional counterpart in various information-processing tasks. However, to harness these advantages, it i…
