Scientists Develop Nanometer Domain N-Slit Quantum Interferometers

Researchers led by physicist F.J. “Frank” Duarte — credited with the 1993 invention of the N-slit laser interferometer — have designed practical N-slit quantum interferometers in the nanometer domain. The work, which the researchers said marks the first development of such quantum interferometers for operation at nanometer dimensions, charts a course for the development of quantum interferometers capable of differentiating spatial features down at femtometer-range precision.
