SUMMARY:Exploiting relativity in quantum technologies and how a macroscopi
 c clock can make you younger - Ivette Fuentes (University of Nottingham)

DESCRIPTION:Quantum technologies are widely expected to bring about many k
 ey technological advances this century. Quantum metrology and quantum info
 rmation have been so far successfully applied in the design of devices tha
 t outperform their classical counterparts by exploiting quantum properties
 . Impressively\, the quantum era is now reaching relativistic regimes. Tab
 le-top experiments demonstrate relativistic effects in quantum fields and 
 long range quantum experiments will soon reach regimes where relativity ki
 cks in.  The general expectation is that relativity will produce small eff
 ects in such technologies.\n\nIn this talk I will show how relativistic ef
 fects can be used to improve quantum measurement technologies and implemen
 t universal quantum computation. Experiments are currently taking place to
  demonstrate our results in superconducting circuits. I will also show tha
 t the twin paradox can be demonstrated in this experimental setup.  Our an
 alysis predicts that the spatial extension of clocks and the dynamical Cas
 imir effect make moving clocks tick slower.
