Picture of a Single Atom Wins Top Prize in Science Photo Contest

[ 12 February 2018 ] An image of a single positively-charged strontium atom, impounded near motionless by electrical lands, has won the overall medal in their own nationals science photography contender, organised by the Engineering and Physical Sciences Research Council( EPSRC ).


Single Atom in an Ion Trapa

, by David Nadlinger, from the University of Oxford, shown in the atom held by the fields arising as a result of the metal electrodes bordering it. The distance between the smaller needle tips is about two millimetres.

When illuminated by a laser for the human rights blue-violet emblazon the atom assimilate and re-emits light-footed particles sufficiently soon for an ordinary camera to captivate it in a long show photo. The winning image was taken through a opening of the ultra-high vacuum enclosure that houses the ion trap.

Laser-cooled atomic ions provision a pristine programme for analyse and controlling the unique owneds of quantum physics. They can serve as most accurate clocks and sensors or, as explored by the UK Networked Quantum Information Technologies Hub, as building block for future quantum computers, which could tackle difficulties that stymie even todaya

s largest supercomputers.

The image, came firstly in the Equipment& Facilities category, as well as winning overall against many other impressive illustrations, featuring study in action, in the EPSRCs competition a

now in its fifth year.

David Nadlinger, explained how the photograph came about: a

The plan of being able to see a single atom with the naked nose had struck me as a wonderfully direct and visceral connection between the miniscule quantum world and our macroscopic world. A back-of-the-envelope figuring depicted the numbers to be on my back, and when I set off to the lab with camera and tripods one quiet Sunday afternoon, I was reinforced with this particular picture of a small, pale blue dot.a
