NIST Team Compares 3 Top Atomic Clocks With Record Accuracy Over Both Fiber and Air

“In a significant advance toward the future redefinition of the international unit of time, the second, a research team led by the National Institute of Standards and Technology (NIST) has compared three of the world’s leading atomic clocks with …

Optical Fiber Could Boost Power of Superconducting Quantum Computers

“The secret to building superconducting quantum computers with massive processing power may be an ordinary telecommunications technology — optical fiber. Physicists at the National Institute of Standards and Technology (NIST) have measured and controlled a superconducting quantum bit (qubit) using light-conducting …

As Good as it Gets: NIST Develops Its Fourth Generation Wire Micrometer that Rivals Best in the World

“Researchers at the National Institute of Standards and Technology (NIST) have developed a dramatically improved laser-based instrument that measures the diameter of fine-gauge wires, fibers and other objects only about three times the thickness of a human hair. Known as …

A Better Way to Measure Acceleration

“NIST researchers rely on a light touch. You’re going at the speed limit down a two-lane road when a car barrels out of a driveway on your right. You slam on the brakes, and within a fraction of a …

Bringing Atoms to a Standstill: NIST Miniaturizes Laser Cooling

“It’s cool to be small. Scientists at the National Institute of Standards and Technology (NIST) have miniaturized the optical components required to cool atoms down to a few thousandths of a degree above absolute zero, the first step in …

JILA’s Bigger and Better ‘Tweezer Clock’ Is Super Stable

“JILA physicists have boosted the signal power of their atomic “tweezer clock” and measured its performance in part for the first time, demonstrating high stability close to the best of the latest generation of atomic clocks. The unusual clock, which …

JILA’s Electric ‘Knob’ Tunes Chemical Reaction Rates in Quantum Gas

“Building on their newfound ability to induce molecules in ultracold gases to interact with each other over long distances, JILA researchers have used an electric “knob” to influence molecular collisions and dramatically raise or lower chemical reaction rates. These super-chilly …

New JILA Tools ‘Turn On’ Quantum Gases of Ultracold Molecules

“JILA researchers have developed tools to “turn on” quantum gases of ultracold molecules, gaining control of long-distance molecular interactions for potential applications such as encoding data for quantum computing and simulations. The new scheme for nudging a molecular gas down …

NIST Sensor Experts Invent Supercool Mini-Thermometer

“Researchers at the National Institute of Standards and Technology (NIST) have invented a miniature thermometer with big potential applications, such as monitoring the temperature of processor chips in superconductor-based quantum computers, which must stay cold to work properly. NIST’s …

Thermal MagIC: New NIST Project to Build Nano-Thermometers Could Revolutionize Temperature Imaging

“Cheaper refrigerators? Stronger hip implants? A better understanding of human disease? All of these could be possible and more, someday, thanks to an ambitious new project underway at the National Institute of Standards and Technology (NIST). NIST researchers are in …
