Entanglement between quantum dots transmitted via Majorana wire: Insights from the fermionic negativity, concurrence and quantum mutual information
The study investigates quantum entanglement between two quantum dots connected by a topological superconducting nanowire hosting Majorana modes. Researchers used fermionic negativity, thermal concurrence, and mutual information to quantify entanglement under different energy levels and hybridization conditions. Findings show optimal entanglement occurs when dot energies align with Majorana modes or at specific coupling strengths.
