Future quantum technologies may exploit identical particle entanglement

15.06. 2018 Quantum Physics News

Usually when physicists perform quantum entanglement between particles—whether it be qubits, atoms, photons, electrons, etc.—the particles are distinguishable in some way. Only recently have physicists demonstrated the feasibility of generating entanglement between particles that are completely identical. Interestingly, this entanglement exists just because of the indistinguishability of the particles, without any interaction between them.

New algorithm can discover materials with unusual characteristics—including invisibility

15.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Metamaterials are artificially engineered materials. Scientists create them by combining multiple elements from composite materials such as a metal and an electrical insulator. The result is an entirely new material with properties not found in nature. Engineers can then use these materials to create new devices or improve existing ones.

Biological light sensor filmed in action

15.06. 2018 Optics & Photonics News - Optics, Photonics, Physics News

Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor retinal is activated in a protein molecule. Such reactions occur in numerous organisms that use the information or energy content of light – they enable certain bacteria to produce energy through photosynthesis, initiate the process of vision in humans and animals, and regulate adaptations to the circadian rhythm. The movie shows for the first time how a protein efficiently controls the reaction of the embedded light sensor. The images, now published in the journal Science, were captured at the free-electron X-ray laser LCLS at Stanford University in California. Further investigations are planned at SwissFEL, the new free-electron X-ray laser at PSI. Besides the scientists from Switzerland, researchers from Japan, the USA, Germany, Israel, and Sweden took part in this study.

Plants open their pores and scientists strike gold

14.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Plants containing the element gold are already widely known. The flowering perennial plant alfafa, for example, has been cultivated by scientists to contain pure gold in its plant tissue. Now researchers from the Sun Yat-sen University in China have identified and investigated the characteristics of gold nanoparticles in two plant species growing in their natural environments. The study, led by Xiaoen Luo, is published in Springer's journal Environmental Chemistry Letters and has implications for the way gold nanoparticles are produced and absorbed from the environment.
