Atomic clocks are the best sensors mankind has ever built. Today, they can be found in national standards institutes or satellites of navigation systems. Scientists all over the world are working to further optimize the precision of these clocks. Now, a research group led by Peter Zoller, a theorist from Innsbruck, Austria, has developed a new concept that can be used to operate sensors with even greater precision irrespective of which technical platform is used to make the sensor. \u201cWe answer the question of how precise a sensor can be with existing control capabilities, and give a recipe for how this can be achieved,\u201d explain Denis Vasilyev and Raphael Kaubr\u00fcgger from Peter Zoller\u2019s group at the Institute of Quantum Optics and Quantum Information at the Austrian Academy of Sciences in Innsbruck.<\/p>\n

For this purpose, the physicists use a method from quantum information<\/a> processing: Variational quantum algorithms describe a circuit of quantum gates that depends on free parameters. Through optimization routines, the sensor autonomously finds the best settings for an optimal result. \u201cWe applied this technique to a problem from metrology\u2014the science of measurement,\u201d Vasilyev and Kaubr\u00fcgger explain. \u201cThis is exciting because historically advances in atomic physics<\/a> were motivated by metrology, and in turn quantum information processing<\/a> emerged from that. So, we\u2019ve come full circle here,\u201d Peter Zoller says. With the new approach, scientists can optimize quantum sensors to the point where they achieve the best possible precision technically permissible.<\/p>\n","protected":false},"excerpt":{"rendered":"
