contest<span class=\"media-credits\">Diana Prado Lopes Aude Craik\/University of Oxford  <\/span><\/p><\/div>\n<p>Brazilian physicist Diana Prado Lopes Aude Craik, 28, who is pursuing a Ph.D. in quantum physics at the University of Oxford in England, has won first place in the Eureka category (images that reflect new discoveries), as well as the top prize in a science photography contest sponsored by the Engineering and Physical Sciences Research Council (EPSRC), a British agency that funds research in the fields of engineering and physical science.\u00a0 With a photo of a gold microchip used to trap ions in quantum computing experiments, designed by herself and a colleague at the university, Craik outperformed more than 200 contestants.\u00a0 The winning image showcases the chip&#8217;s golden filaments, connected to electrodes that transmit electrical fields in order to trap individual ions about 100 microns above the surface of the device.\u00a0 \u201cIndividual atomic ions can be trapped when electric potential is applied to the chip&#8217;s gold electrodes.\u00a0 These ions are used as quantum bits \u2013 or qubits, for short \u2013, the units that store and process information in a quantum computer,\u201d said Craik, after being announced the winner of the contest.\u00a0 \u201cTwo states of energy of a trapped ion serve as [positions] 0 and 1 of a qubit.\u00a0 Electrodes built into the microchip transmit microwave radiation to the ions, making it possible to manipulate the stored quantum information by stimulating the transition between energy states 0 and 1.\u201d\u00a0 The device was produced by photolithography, a technique used in making integrated circuits.\u00a0 Having been awarded the top prize, Craik won \u00a3 500 (R$2,537.00) in photographic materials.<\/p>\n","protected":false},"excerpt":{"rendered":"Brazilian physicist has won two prizes in United Kingdom
