Fast Track Control Accelerates Switching of Quantum Bits

Quantum_bit_image_940x823.jpg

An international collaboration among physicists at the University of Chicago, Argonne National Laboratory, McGill University and the University of Konstanz recently demonstrated a new framework for faster control of a quantum bit—the basic unit of information in yet-to-be created quantum computers—in findings published online Nov. 28 in Nature Physics. Their experiments on a single electron in a diamond chip could create quantum devices less prone to errors when operated at high speeds.

Zeroing in on the True Nature of Fluids Within Nanocapillaries

JCP-Morineau-core-shell-structure.png

Shrinking the investigation of objects to the nanometer scale often reveals new properties of matter that have no equivalent for their bulk analysis. This phenomenon is motivating studies of nanomaterials which can reveal fascinating new phenomena. It inspired researchers to explore the extent of knowledge about fundamental properties of fluids, which demands reconsideration with the increasing use of fluids in the decreasing sizes of new devices, where their flow is confined into ever-smaller capillary tubes.
