Quantum computer ion trap photo wins EPSRC prize

A photo of a gold ion trap has won the Engineering and Physical Sciences Research Council (EPSRC) science photography competition.

Quantum computer ion trap photo wins EPSRC prize

‘Microwave ion-trap chip for quantum computation’, by Diana Prado Lopes Aude Craik and Norbert Linke of the University of Oxford, shows the chip’s gold wire-bonds connected to electrodes whose electric fields trap single ions 100µmicrons above their surface for quantum computing.

“These ions are used as quantum bits which store and process information in a quantum computer. Slotted electrodes on the chip deliver microwave radiation to the ions, allowing us to manipulate the stored quantum information by exciting transitions between the ‘0’ and ‘1’ energy states,” said Craik, who added that the Oxford team recently achieved the ‘world’s highest-performing qubits and quantum logic operations’.

The competition’s five categories were: Eureka, Equipment, People, Innovation, and Weird and Wonderful.

The ion trap was also first in the Eureka category.
