    A Rutgers-led team of physicists has demonstrated a way to conduct electricity between transistors without energy loss, opening the door to low-power electronics and, potentially, quantum computing that would be far faster than today’s computers. Their findings, which involved using a special mix of materials with magnetic and insulator properties, are published online in Nature Physics.

    Scientists have achieved, in an experiment, quantum entanglement between 2 Bose-Einstein condensates, spatially separated from each other. Quantum entanglement was discovered by Schrödinger and later studied by Einstein and other scientists in the last century. The groups of entangled particles lose their individuality and behave as a single entity. Any change in one of the particles leads to an immediate response in the other, even if they are spatially separated...

    The experimental realization of ultrathin graphene – which earned two scientists from Cambridge the Nobel Prize in physics in 2010 – has ushered in a new age in materials research. What started with graphene has evolved to include numerous related single-atom-thick materials, which have unusual properties due to their ultra-thinness...

    Single Atom Memory: The World’s Smallest Storage Medium

    March 9, 2017, Categories  Physics, Technology/Electronics

    A holmium (Ho) and a iron (Fe) atom placed on a MgO substrate are the components for the world's smallest memory device. Ho is used as a storage medium and Fe as a sensor were. The magnetism of the holmium atom can be changed or read by flowing current through the STM tip.

    Storing 1 bit in 1 atom is possible: The extraordinary end of Moore’s law. One bit of digital information can now be successfully stored in an individual atom, according to a study just published in Nature. Current commercially-available magnetic memory devices require approximately 1 million atoms to do the same...
