Andrew Shields

from Wikipedia, the free encyclopedia

Andrew James Shields is a British physicist. He works in Toshiba Europe's research laboratories .

Shields received his degree in physics from Imperial College London in 1985 and received his PhD there in 1990. He heads the quantum information group at Toshiba Research Europe. In 2012 he was Assistant Managing Director.

In 2005 he and colleagues at Toshiba developed a detector for single photons based on a quantum dot in a tunnel diode . He and colleagues also developed the first voltage-controlled sources for individual photons in light-emitting diodes with quantum dots .

At Toshiba, in collaboration with the Cavendish Laboratory in Cambridge, Shields developed the Entangled light emitting diode , an LED source for entangled photon pairs that can be electrically controlled via a quantum dot .

In 2012, his group at Toshiba managed to transfer the conventional stream of data signals and the photons required for quantum cryptography (which represented a very weak signal compared to the data stream) on the same conventional fiber optic cables. This was achieved with a detector for individual photons, which was only ready to receive for a very short period of time (at the expected time of arrival of the photo signal).

In 2013 he received the Mott Medal for research in semiconductors, fiber optics and quantum information theory.
