Next Scientific Fashion Could be Designer Nanocrystals

Three University of Chicago chemistry professors hope that their separate research trajectories will converge to create a new way of assembling what they call “designer atoms” into materials with a broad array of potentially useful properties and functions.

These “designer atoms” would be nanocrystals—crystalline arrays of atoms intended to be manipulated in ways that go beyond standard uses of atoms in the periodic table. Such arrays would be suited to address challenges in solar energy, quantum computing and functional materials. (more…)

Yale Research Offers New Way To See Inside Solids

Researchers at Yale University have developed a new way of seeing inside solid objects, including animal bones and tissues, potentially opening a vast array of dense materials to a new type of detailed internal inspection.

The technique, a novel kind of magnetic resonance imaging (MRI), creates three-dimensional images of hard and soft solids based on signals emitted by their phosphorus content. (more…)

At Yale, Quantum Computing is a (qu)bit Closer to Reality

Physicists at Yale University have taken another significant step in the development of quantum computing, a new frontier in computing that promises exponentially faster information processing than the most sophisticated computers of today.

In research published online this month in the journal Nature, the Yale physicists demonstrate the most basic form of quantum error correction — a way to compensate for quantum computing’s intrinsic susceptibility to errors. Developing technology to correct these errors on the fly is a necessary step for fully realizing quantum computers. (more…)

Yale’s New Microscope Brings Atoms’ Identities into Focus

Yale’s acquisition of a powerful new transmission electron microscope (TEM) is expected to transform researchers’ ability to examine and manipulate atom-scale materials and devices on campus.

The approximately $2 million, state-of-the-art microscope offers atomic resolution for both physical structure and chemical composition, as well as significantly faster processing times than other devices on campus. It is the first unit of this specific TEM model acquired for university laboratory use. (more…)

Flipping an Egg Carton of Light Traps Giant Atoms

ANN ARBOR, Mich.— In an egg carton of laser light, University of Michigan physicists can trap giant Rydberg atoms with up to 90 percent efficiency, an achievement that could advance quantum computing and terahertz imaging, among other applications.

Highly excited Rydberg atoms can be 1,000 times larger than their ground state counterparts. Nearly ionized, they cling to faraway electrons almost beyond their reach. Trapping them efficiently is an important step in realizing their potential, the researchers say.

Here’s how they did it: (more…)

Diamonds, Silver and the Quest for Single Photons

*Tiny crystal towers enlighten understanding of photon emission, could inspire diamond microchips for quantum computing*

Building on earlier work, scientists and engineers recently developed a manufacturing process that allows them to craft an assortment of miniature, silver-plated-diamond posts that enable greater control of light producing photons at the atomic scale. The research could prove important for future generations of quantum computers.

Prior research demonstrated how nanowires carved in impurity-laden diamond crystal could efficiently emit individual photons, an important discovery for using light to rapidly read and write quantum-based data. (more…)

‘On Quest for Information Science’s Holy Grail: Quantum Computing’

*Q & A: Dr. Michael Freedman discusses his past accomplishments and current pursuits to build a quantum computer.*

Santa Barbara, Calif. Mountain climbing is all about testing and pushing limits. But it’s not enough to rely on physical strength and stamina alone. To conquer a mountain, one must also possess the mental toughness and problem-solving skills needed to navigate difficult, potentially dangerous, terrain. (more…)
