Bethe String Observed Experimentally

Authors: George Rajna

An international team of researchers has experimentally observed Bethe strings for the first time. [21] Understanding the causes and effects of the friction could pave the way for explorations into the composition of neutron stars and our universe. Here on Earth, the Aalto researchers' results will be invaluable for curtailing the production of heat and unwanted glitches in quantum computer components. [20] A half-quantum vortex combines circular spin flow and circular mass flow, leading to the formation of vortex pairs that can be observed experimentally. [19] Intricately shaped pulses of light pave a speedway for the accelerated dynamics of quantum particles, enabling faster switching of a quantum bit. [18] An international team of scientists has succeeded in making further improvements to the lifetime of superconducting quantum circuits. [17] A Yale-led group of researchers has derived a formula for understanding where quantum objects land when they are transmitted. [16] The scheme is based on the ideas of physicist David J. Thouless, who won half the 2016 Nobel Prize in physics for his work on topological effects in materials. Topological effects are to do with geometry, and their use in quantum computing can help protect fragile quantum states during processing. [15] Now a researcher and his team at Tyndall National Institute in Cork have made a 'quantum leap' by developing a technical step that could enable the use of quantum computers sooner than expected. [14] A method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications has gained momentum with a demonstration by researchers at the Department of Energy's Oak Ridge National Laboratory. [13] A source of single photons that meets three important criteria for use in quantum-information systems has been unveiled in China by an international team of physicists. Based on a quantum dot, the device is an efficient source of photons that emerge as solo particles that are indistinguishable from each other. The researchers are now trying to use the source to create a quantum computer based on "boson sampling". [11]
