WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational … WebFor example, chiral lasing and quantum entanglement. [31, 32] To address this challenge, the idea of combining high-Q quasi-BICs resonances with chirality seems promising. To this end, several pioneering studies reported on the creation of chiral quasi-BIC resonances with giant circular dichroism (CD) in dielectric platforms.

Chirality (from the Greek word cheir, meaning “ hand ”) is the geometric property displayed by any object that is non-superimposable on its mirror image. The main structural feature responsible for chirality is the presence of dissymmetry; as it has no plane of symmetry (as previously explained).
