Resource theory of imaginarity: Quantification and state conversion
Kang-Da Wu, Tulja Varun Kondra, Swapan Rana +5
Complex numbers are widely used in both classical and quantum physics, and are indispensable components for describing quantum systems and their dynamical behavior. Recently, the r…
Operational Resource Theory of Imaginarity
Kang-Da Wu, Tulja Varun Kondra, Swapan Rana +5
Wave-particle duality is one of the basic features of quantum mechanics, giving rise to the use of complex numbers in describing states of quantum systems, their dynamics, and inte…
Entanglement negativity as a universal non-Markovianity witness
Jan Kolodynski, Swapan Rana, Alexander Streltsov
In order to engineer an open quantum system and its evolution, it is essential to identify and control the memory effects. These are formally attributed to the non-Markovianity of…
Optimal decomposition of incoherent qubit channel
Swapan Rana, Maciej Lewenstein
We show that any incoherent qubit channel could be decomposed into four incoherent Kraus operators. The proof consists in showing existence of four incoherent Kraus operators by de…
Entanglement and coherence in quantum state merging
A. Streltsov, E. Chitambar, S. Rana +3
Understanding the resource consumption in distributed scenarios is one of the main goals of quantum information theory. A prominent example for such a scenario is the task of quant…
N-Qubit W States are Determined by their Bipartite Marginals
Preeti Parashar, Swapan Rana
We prove that the most general W class of N-qubit states are uniquely determined among arbitrary states (pure or mixed) by just their bipartite reduced density matrices. Moreover,…
