A certain kind of material, called a topological insulator, acts partially like one and partially like the other-it behaves like a conductor at its surface and an insulator in its interior.  Topological insulators (TIs) host exotic physics that could shed new light on the fundamental laws of nature.  A new study by scientists from the University of Bristol brings us a significant step closer to unleashing the revolutionary potential of quantum computing by harnessing silicon fabrication technology to build complex on-chip quantum optical circuits.  Two teams of scientists from the Technion-Israel Institute of Technology have collaborated to conduct groundbreaking research leading to the development of a new and innovative scientific field: Quantum Metamaterials.  An international team consisting of Russian and German scientists has made a breakthrough in the creation of seemingly impossible materials. They have created the world's first quantum metamaterial that can be used as a control element in superconducting electrical circuits.  ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product.  Cheng Chin, professor in the Department of Physics, and his team looked at an experimental setup of tens of thousands of atoms cooled down to near absolute zero. As the system crossed a quantum phase transition, they measured its behavior with an extremely sensitive imaging system.  Scientists from three UK universities are to test one of the fundamental laws of physics as part of a major Europe-wide project awarded more than £3m in funding. ]19] A team of researchers has devised a simple way to tune a hallmark quantum effect in graphene-the material formed from a single layer of carbon atoms-by bathing it in light.
