A step towards quantum electronics
Work of physicists at the University of Geneva (UNIGE), Switzerland, and the Swiss Federal Institute of Technology in Zurich (ETH Zurich), in which they connected two materials with unusual quantum-mechanical properties through a quantum constriction, could open up a novel path towards both a deeper understanding of physics and future electronic devices. Their results have just been published in the journal Science.

NIST Adds to Quantum Computing Toolkit with Mixed-Atom Logic Operations
Physicists at the National Institute of Standards and Technology (NIST) have added to their collection of ingredients for future quantum computers by performing logic operations—basic computing steps—with two atoms of different elements. This hybrid design could be an advantage in large computers and networks based on quantum physics.

Oxford team demonstrates 'hybrid' logic gate as work towards quantum computer continues
Just over a year ago, the UK government announced an investment of £270m over five years to help get quantum technology out of laboratories and into the marketplace.
Oxford was chosen to lead one of four EPSRC-funded 'Hubs' looking at different aspects of quantum technology – in Oxford's case, shaping the future of quantum networking and computing, towards the ultimate goal of developing a functioning quantum computer.
