Quantum logic is quite a new and absolutely fascinating field of physics and might - ultimately - lead to the fabrication of a quantum computer. And it could also aid the search for the "theory of everything" - the missing link between traditional physics and quantum physics. One of the fundamental questions hereby is whether fundamental constants possibly vary. To prove this in the case of the fine-structure constant, for instance, we have to measure the spectral lines of atoms (i.e. their...

New technique has potential to simplify future 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. By directly linking the motions of two physically separated atoms, the technique has the potential to simplify information processing in future quantum computers and simulations. Described in a...

Despite a steady improvement in the speed of conventional computers during the last few decades, certain types of problems remain computationally difficult to solve. Quantum computers hold the promise of offering a new route to solving some classes of these problems, such as breaking encryptions. The tremendous computing power of these devices stems from their use of quantum systems, called "qubits," which can exist in a "superposition" of two states at the same time "“ in stark...

Physicists at the National Institute of Standards and Technology (NIST) have built and tested a device for trapping electrically charged atoms (ions) that potentially could process dozens of ions at once with the most versatile control of any trap demonstrated to date. The novel design is a first attempt to systematically scale up from traps that hold a few ions in a few locations to large trap arrays that can process many ions simultaneously, with the ultimate goal of building a practical...

Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the National Institute of Standards and Technology (NIST) could usher in a new generation of applications because the device holds promise as a stylus for sensing very small forces or as an interface for efficient transfer of individual light particles for quantum communications.The "stylus trap," built by...

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a new ion trap that enables ions to go through an intersection while keeping their cool. Ten million times cooler than in prior similar trips, in fact. The demonstration, described in a forthcoming paper in Physical Review Letters,* is a step toward scaling up trap technology to build a large-scale quantum computer using ions (electrically charged atoms), a potentially powerful machine that could perform...

  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
