Quantifying the Parameterized Monogamy Relation for Quantum Entanglement with Equation
An extended concept of monogamy for the square of entanglement measure E is introduced in our work. Instead of the traditional CKW inequality, we build a monogamy connection based on the parameters \(\mu \), from which we obtain a monogamy relationship satisfied by the \(\alpha \)th (\(\alpha \ge 2\)) power of the entanglement measures. We use concrete instances to highlight the significance and advantages of these relation. We further show that monogamy relationship may be restored by considering multiple state copies for each nonadditive entanglement measurement that violates the CKW inequality. We also demonstrate how the relationship between tripartite states and multiparty systems might be strengthened.
期刊介绍:
International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
