Tom Heavner is a physicist at NIST who specializes in precision timekeeping using quantum technologies. He joined the institute in 1998 after earning a Ph.D. in physics, bringing expertise in studying single ions. His work focuses on improving atomic clocks, which are devices that use quantum properties to measure time with extreme accuracy.
Currently, Heavner is leading a project to incorporate a strontium ion optical clock into the NIST timescale. This represents a shift from traditional cesium clocks to more advanced light-based systems that offer better stability. The technology is being actively integrated to improve the national timescale.
This advancement improves the reliability of national timekeeping systems, which supports various scientific and technological fields. While it does not establish a new computing protocol, it enhances the underlying infrastructure for precise measurement. The implementation is ongoing, with results expected to refine how time is distributed and measured.
