  1. Computing Faster With Quasi-Particles

    In collaboration with researchers from Harvard University, researchers from the University of Würzburg have made an important step on the road to topological quantum computers. Now, they present their findings in the renowned scientific journal Nature.

  2. Researchers Can Now Tell How Accurate Two-Qubit Calculations In Silicon Really Are

    After being the first team to create a two-qubit gate in silicon in 2015, UNSW Sydney engineers are breaking new ground again: they have measured the accuracy of silicon two-qubit operations for the first time – and their results confirm the promise of silicon for quantum computing.

  3. Earth's Magnetic Field Measured Using Artificial Stars At 90 Kilometers Altitude

    The mesosphere, at heights between 85 and 100 kilometers above the Earth's surface, contains a layer of atomic sodium. Astronomers use laser beams to create artificial stars, or laser guide stars (LGS), in this layer for improving the quality of astronomical observations.

  5. Physicists Propose Perfect Material For Lasers

    Weyl semimetals are a recently discovered class of materials, in which charge carriers behave the way electrons and positrons do in particle accelerators. Researchers from the Moscow Institute of Physics and Technology and Ioffe Institute in St. Petersburg have shown that these materials represent perfect gain media for lasers.

  6. How To Create A Spotlight Of Sound With LEGO-Like Bricks

    Academics have created devices capable of manipulating sound in the same way as light – creating exciting new opportunities in entertainment and public communication.

  7. Quantum Sensor For Photons

    A photodetector converts light into an electrical signal, causing the light to be lost. Researchers led by Tracy Northup at the University of Innsbruck have now built a quantum sensor that can measure light particles non-destructively.

  8. Quantum Computing With Graphene Plasmons

    A novel material that consists of a single sheet of carbon atoms could lead to new designs for optical quantum computers. Physicists from the University of Vienna and the Institute of Photonic Sciences in Barcelona have shown that tailored graphene structures enable single photons to interact with each other.

  9. Spin Waves Pair Up Like Photons

    When two identical photons arrive at a half-reflecting piece of glass, in the quantum mechanical world they are always either both transmitted or reflected - they pair up. This effect, termed Hong-Ou-Mandel interference, should occur not only for photons, but for any bosons.

  10. Generating High-Quality Single Photons For Quantum Computing

    MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers.
