Abstract

How do we bridge the gap between the exquisitely tested quantum theory of the small and the very classical experience of our us sized lives Is some modification needed to quantum theory and if so where is it to be found Successive tests of the Leggett Garg inequality have failed to reveal macrorealism in the experiments which have been performed Could a more sensitive experiment reveal a discrepancy such as continuous spontaneous localisation Such an experiment could soon be within reach in an ion trap References The Oxford Questions on the foundations of quantum physics Proc R Soc A 469 20130299 2013 G A D Briggs J N Butterfield and A Zeilinger Violation of a Leggett Garg inequality with ideal non invasive measurements Nat Commun 3 606 2012 G C Knee S Simmons E M Gauger J J L Morton H Riemann N V Abrosimov P Becker H J Pohl K M Itoh M L Thewalt G A D Briggs and S C Benjamin Opening up three quantum boxes causes classically undetectable wavefunction collapse Proc Natl Acad Sci USA 110 3777 3781 2013 R E George L Robledo O J E Maroney M Blok H Bernien M L Markham D J Twitchen J J L Morton G A D Briggs and R Hanson Detecting continuous spontaneous localisation with charged bodies in a Paul trap Y Li A M Steane D Bedingham and G A D Briggs http: arxiv org pdf 1605 01881 pdf Bio Professor Andrew Briggs is the inaugural holder of the Chair in Nanomaterials at the University of Oxford In 1999 he was elected Honorary Fellow of the Royal Microscopical Society for his innovative techniques and applications of microscopy From 2002 2009 he was Director of the Interdisciplinary Research Collaboration in Quantum Information Processing which served to create new experimental and theoretical capacity in the UK and was followed in 2013 by a UK government investment of 270M in Quantum Technologies His research interests focus on nanomaterials for new technologies and their incorporation into practical devices He uses similar materials and techniques for experimental tests of interpretations of reality His laboratory studies single molecule devices for low energy information and communication technologies and for simulating quantum processes in biology He has nearly 600 publications with over 16 000 citations In February 2016 Oxford University Press published his book with Roger Wagner entitled The Penultimate Curiosity: How science swims in the slipstream of ultimate questions
