Exclusion reshapes the operational manifestation of preparation contextuality
Pritam Roy, Thansingh Jankawat, Ranendu Adhikary +1
Replacing the task of retrieval with exclusion changes how preparation contextuality manifests operationally under parity-oblivious constraints, with exclusion showing a quantum ad…
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…
Decoherence from quantum spacetime noise: An open-systems framework with application to neutrino oscillations
Partha Nandi, Tiasha Bhattacharyya, A. S. Majumdar +2
We present a general open-quantum-systems framework to model decoherence induced by stochastic Planck-scale fluctuations of spacetime, focusing on the kappa-Minkowski noncommutativ…
Magnetically Induced Schrödinger Cat States: The Shadow of a Quantum Space
Partha Nandi, Nandita Debnath, Subhajit Kala +1
Schrödinger cat states, which are superpositions of macroscopically distinct states, are potentially critical resources for upcoming quantum information technologies. In this paper…
