The article discusses the legacy of physicist Dave Wineland and his groundbreaking work at NIST, particularly in developing ultraprecise atomic clocks and quantum computing technologies. Wineland’s team pioneered the use of laser-cooled atoms and ions to create clocks that are accurate to within a second in millions of years, with applications in GPS navigation, fundamental physics measurements, and potentially even quantum computing.
Wineland’s research group at NIST has been at the forefront of developing quantum computing technologies using trapped ions. They have made significant advances in quantum entanglement, error correction, and quantum control, which have inspired researchers worldwide. However, Wineland cautions that a practical quantum computer is still some distance away, comparing it to a marathon race where the finish line is still in sight.
In addition to his work on atomic clocks and quantum computing, Wineland has made important contributions to testing predictions of Einstein’s relativity theory using ultraprecise clocks. His team has demonstrated that time slows down for objects moving faster or in stronger gravitational fields, even at relatively slow speeds and small heights.
Wineland’s impact on NIST has been profound, and his departure after 42 years at the agency is bittersweet. He will be taking on a new role as a Knight research professor at the University of Oregon, while continuing to collaborate with NIST researchers.
