"chiral fermionic valve spatially separating quantum particles of opposite chirality using quantum geometry alone, combining materials with exceptional topological quality/ transport attributes at mesoscopic quantum limit... electric current applied to palladium-gallium hosting multifold fermions generates chirality-dependent velocities controlling fermionic chirality; separated chiral currents remain phase coherent over >15 µm... information encoded/ processed using quantum states' handedness"
