World Record Set with Largest Quantum Register Ever Produced

Quantum physicists from the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced.

Samsung Creates Full-Color Display Using Quantum Dots

Samsung Electronics Co. has succeeded in developing the world's first full-color display using quantum dots, paving the way for producing large displays that are brighter, cheaper and more advanced.

JILA Scientists Eliminate Collisions Between Atoms in an Atomic Clock

In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery, described in the Feb. 3 issue of Science Express, can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams.

Researchers Entice Two Atoms to Swap Smallest Energy Units, Potential to Simplify Information Processing

Physicists at the National Institute of Standards and Technology (NIST) have for the first time coaxed two atoms in separate locations to take turns jiggling back and forth while swapping the smallest measurable units of energy.

Quantum Logic Clock Now World's Most Precise Clock

Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that is now the world's most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom.
