I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Buried GitHub archival storage to last 1,000 years” Credit: Pixabay/CC0 Public Domain If civilization ever succumbs to global warming, nuclear annihilation, an unrelenting pandemic or a martian invasion, some future civilization—or alien life form—might well still be able to reconstruct today’s computers and compose advanced machine learning algorithms … and perhaps even play a round…
“#Quantum exciton found in magnetic van der Waals material” Fig. 1-a (Top) The crystal structure of NiPS3 ; Fig. 1-b (Down) An exciton state proposed for NiPS3.

“#Scientists strengthen quantum building blocks in milestone critical for scale-up” The circular orbit of the charged electron and the spin are locked together like gears due to the very strong attraction in the spin-orbit coupling. Credit: Takashi Kobayashi A group of international scientists have substantially lengthened the duration of time that a spin-orbit qubit in…
“#Scientists achieve major breakthrough in preserving integrity of sound waves” Credit: CC0 Public Domain In a breakthrough for physics and engineering, researchers from the Photonics Initiative at the Advanced Science Research Center at The Graduate Center, CUNY (CUNY ASRC) and from Georgia Tech have presented the first demonstration of topological order based on time modulations….
“#Streamlining quantum information transmission” A tele-meeting with the results: from left, William J. Munro, Nicolò Lo Piparo, Kae Nemoto, Michael Hanks, and Claude Gravel. Credit: Kae Nemoto, Global Research Center for Quantum Information Science, the National Institute of Informatics in Japan The quantum realm holds the key to the next revolution in communication technology as…
“#Rsearchers suggest modification of quantum encryption system with compact detector” Credit: Bruno Thethe on Unsplash A new system can significantly lower the production costs costs of mass quantum key distribution (QKD) networks, which will make them available to a wider user audience. This will make it possible to use QDK in the regular fiber-optic cable…
“#Hammer-on technique for atomic vibrations in a crystal” Fig. 1. Unit cell (a cube having an edge length of 0.56 nm [one millionth of 0.56 mm]) of gallium arsenide with gallium (black) and arsenic atoms (red) connected by covalent bonds (blue). A gallium arsenide crystal consists of many billions of such unit cells. Credit: MBI…
“#Tiny bubbles make a quantum leap” Schematic of a laser-illuminated nano-optical probe investigating a strained nanobubble of tungsten diselenide (WSe2; green and yellow balls), a 2-dimensional semiconductor. The single layer of WSe2 is sitting on a layer of boron nitride (blue and grey balls). Credit: Nicholas Borys/Montana State University July 13, 2020—Researchers at Columbia Engineering…
“#Cherned up to the maximum” Crystals of PdGa can be grown with two distinctstructural chiralities (left and right column). The two enantiomers have mirrored crystalstructures (second row), as seen in electron-reflection patterns (third row). Schröter et al. nowdemonstrate that the handedness are reflected as well in the structure of the Fermi surfaces(bottom row), which determine…
“#The spin state story: Observation of the quantum spin liquid state in novel material” A QSL state can be experimentally observed, which has advanced our knowledge of spin behavior, and its integration in next-generation “spintronic” devices. Credit: Tokyo University of Science Aside from the deep understanding of the natural world that quantum physics theory offers,…
