Toward ‘perfect’ quantum metamaterial: Study uses trapped atoms in an artificial crystal of light

May 11, 2016
Scientists take a major leap toward a 'perfect' quantum metamaterial
The wavelike pattern at the top shows the accordion-like structure of a proposed quantum material — an artificial crystal made of light — that can trap atoms in regularly spaced nanoscale pockets. These pockets can be made to hold a large …more

Scientists have devised a way to build a “quantum metamaterial”—an engineered material with exotic properties not found in nature—using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors.

The research team, led by scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley, proposes the use of an accordion-like atomic framework, or “lattice” structure, made with laser light to trap atoms in regularly spaced…
