The standard method for creating them involves crossing six laser beams to generate a 3D interference pattern that traps atoms in either the high-or low-intensity spots (see <a target=\"xrefwindow\" href=\"https:\/\/physics.aps.org\/articles\/v8\/s85\" id=\"d5e116\">Synopsis: Pinpointing Qubits in a 3D Lattice<\/a>). These cold-atom systems have been used as precision clocks and as models of condensed-matter systems. However, the spacing between atoms is fixed by the wavelength of the light, which can limit the control researchers have over the atomic behavior.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new kind of 3D optical lattice traps atoms using focused laser spots replicated in multiple planes and could eventually serve as a quantum computing platform.
