Robust entanglement measure for mixed quantum states
Dharmaraj Ramachandran, Aditya Dubey, Subrahmanyam S. G. Mantha +1
We introduce an entanglement measure, the Modified Bloch Norm (MBN), for finite-dimensional bipartite mixed states, based on the improved Bloch matrix criteria. MBN is demonstrated…

Ab-Initio Approach to Many-Body Quantum Spin Dynamics
Aditya Dubey, Zeki Zeybek, Fabian Köhler +2
A fundamental longstanding problem in studying spin models is the efficient and accurate numerical simulation of the long-time behavior of larger systems. The exponential growth of…
