Optical lattice

Scientists in South Korea have created what they call "the world’s smallest ball game," throwing individual atoms between two optical traps. The research could eventually make for more adaptable and dynamic quantum computers.

With properties that seemingly defy normal physics, Helium-4 superfluid has long defied practical demonstrations of its theorized quasiparticle structure. Now physicists claim to have synthesized this structure in a laser latticed, super-cold superfluid by giving the whole thing a good shake.
