Hourglass nanographenes unlock strong, robust multi-spin entanglement

Phys · · 505 words · By National University

Researchers from the National University of Singapore and international collaborators have developed a design strategy for graphene-like molecules with multiple interacting spins. The study, published in Nature Synthesis, demonstrates the creation of nanographenes with enhanced resilience to magnetic perturbations for potential use in quantum information technologies.
