Im Focus: Using Mirrors to Improve the Quality of Light Particles

Scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute have succeeded in dramatically improving the quality of individual photons generated by a quantum system. The scientists have successfully put a 10-year-old theoretical prediction into practice. With their paper, published recently in Physical Review X, they have taken an important step towards future applications in quantum information technology.

For a number of years, scientists have been working on using electron spins to store and process information. A possible approach is to use a quantum system in...

Im Focus: High-speed Quantum Memory for Photons

Physicists from the University of Basel have developed a memory that can store photons. These quantum particles travel at the speed of light and are thus suitable for high-speed data transfer. The researchers were able to store them in an atomic vapor and read them out again later without altering their quantum mechanical properties too much. This memory technology is simple and fast and it could find application in a future quantum Internet. The journal Physical Review Letters has published the results.

Even today, fast data transfer in telecommunication networks employs short light pulses. Ultra broadband technology uses optical fiber links through which...

Im Focus: Discovery of the most accelerated binary pulsar

Fifty years after Jocelyn Bell discovered the first pulsar, students are no longer going through reams of paper from pen chart recorders but instead search through 1,000s of terabytes of data to find these enigmatic pulsating radio stars. The most extreme binary pulsar system so far, with accelerations of up to 70 g has been discovered by researchers at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn. At their closest approach the orbit of the pulsar and its companion neutron star would easily fit inside the radius of the Sun.

Although most of the more than 2,500 pulsars known are solitary objects, a few are found in tight binary systems. The discovery of the first of these, the...

Im Focus: How receptors for medicines work inside cells

G protein-coupled receptors are the key target of a large number of drugs. Würzburg scientists have now been able to show more precisely how these receptors act in the cell interior.

The human genome encodes hundreds of G protein-coupled receptors (GPCRs). These form the largest group of receptors through which hormones and...

Im Focus: Like a Revolving Door: How Shuttling Proteins Operate Nuclear Pores

Nuclear pore complexes are tiny channels where the exchange of substances between the cell nucleus and the cytoplasm takes place. Scientists at the University of Basel report on startling new research that might overturn established models of nuclear transport regulation. Their study published in the Journal of Cell Biology reveals how shuttling proteins known as importins control the function of nuclear pores – as opposed to the view that nuclear pores control the shuttling of importins.

Genetic information is protected in the cell nucleus by a membrane that contains numerous nuclear pores. These pores facilitate the traffic of proteins known...

Im Focus: Bit data goes anti-skyrmions

Today’s world, rapidly changing because of “big data”, is encapsulated in trillions of tiny magnetic objects – magnetic bits – each of which stores one bit of data in magnetic disk drives. A group of scientists from the Max Planck Institutes in Halle and Dresden have discovered a new kind of magnetic nano-object in a novel material that could serve as a magnetic bit with cloaking properties to make a magnetic disk drive with no moving parts – a Racetrack Memory – a reality in the near future.

Most digital data is stored in the cloud as magnetic bits within massive numbers of magnetic disk drives. Over the past several decades these magnetic bits...

Im Focus: Life-long implants – vision and state of the art

Fraunhofer Institutes FEP and IWU have merged their expertise in order to advance a new generation of medical implants.

Implants are routinely employed in hospitals and dental practices daily. They are technologically mature and offer support for people in many different ways....

Im Focus: Green Light for New 3D Printing Process

Premier at formnext: Additive Manufacturing of Copper Materials Using Selective Laser Melting with Green Light

An innovation in the field of additive manufacturing will make its debut from November 14–17 at this year’s formnext in Frankfurt, Germany: the Fraunhofer...

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
