(NIST: Gaithersburg, MD) -- Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the National Institute of Standards and Technology (NIST) could usher in a new generation of applications, because the device holds promise as a stylus for sensing very small forces or as an interface for efficient transfer of individual light particles for quantum communications.
The NIST "stylus trap" can hold a single ion above any of the three sets of concentric cylinders on the centerline. The device could be used as a stylus with a single atom "tip" for sensing very small forces or an interface for efficient transfer of individual light particles for quantum communications. |
