New research suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennas, which enable the exchange of quantum information between two separate memory cells located on a computer chip. This offers new opportunities to build practical quantum computers.
Experimental physicists have put a lot of effort in isolating sensitive measurements from the disruptive influences of the environment. In an international first, Austrian quantum physicists have realized a toolbox of elementary building blocks for an open-system quantum simulator, where a controlled coupling to an environment is used in a beneficial way. This offers novel prospects for studying the behavior of highly complex quantum systems.
An Austrian research group led by physicist Rainer Blatt suggests a fundamentally novel architecture for quantum computation. They have experimentally
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.
MIT engineers have designed a new type of nanoparticle that could safely and effectively deliver vaccines for diseases such as HIV and malaria. The new
Nanomaterials research could lead to new solutions for an age-old public health problem: how to separate bacteria from drinking water.
Most people cross borders such as doorways or state lines without thinking much about it. Yet not all borders are places of limbo intended only for crossing. Some borders, like those between two materials that are brought together, are dynamic places where special things can happen. For an electron moving from one material toward the other, this space is where it can join other electrons, which together can create current, magnetism or even light. Researchers have made fundamental discoveries at the border regions, called interfaces, between oxide materials.
Scientists have demonstrated a clever way of controlling electrical conductance of a single molecule, by exploiting the molecule
Northwestern University scientists have discovered that axons can operate in reverse: they can also send signals to the neuron cell body, too. Previously, it
It is now possible to see up to 28 differently labeled microbes in a single field of view, due to a new microscopy technique.
How does a scientist fuel his enthusiasm for chemistry after 60 years? By discovering a new energy source, of course.
More than 50 years after the invention of the laser, scientists at Yale University have built the world
Automobiles, military vehicles, even large-scale power generating facilities may someday operate far more efficiently thanks to a new alloy developed at the U.S. Department of Energy
In recent years, topological insulators have become one of the hottest topics in physics. These new materials act as both insulators and conductors, with their interior preventing the flow of electrical currents while their edges or surfaces allow the movement of a charge. Perhaps most importantly, the surfaces of topological insulators enable the transport of spin-polarized electrons while preventing the
