Optical interferometric tools for probing memory effects
Saheli Mukherjee, Bivas Mallick, Samyadeb Bhattacharya +2
Recent efforts to detect non-Markovian memory have become increasingly important, motivated by the broad relevance of memory effects in quantum information processing, metrology, a…
Witness-based quantification of non-Markovianity without complete Choi state reconstruction
Pritam Roy, Saheli Mukherjee, Bivas Mallick
Quantifying non-Markovianity is a fundamental problem in the theory of open quantum systems, as it is essential for exploiting environmental memory as a resource in quantum technol…
Optimal entanglement criteria from trace invariants
Bivas Mallick, Aabhas Gulati, Ion Nechita
Randomized measurement protocols give experimental access to low-degree polynomial invariants of a quantum state rather than to the state itself, which raises the question of what…
Operational certification of nonclassicality in arbitrary quantum states from few copies
Sudip Chakrabarty, Bivas Mallick, Ananda G. Maity +1
States with negative Wigner functions constitute a fundamental nonclassical resource underlying quantum advantage. However, their experimental certification typically relies on rec…
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…
