Long exposure light painting

Smart lighting system based on quantum dots more accurately reproduces daylight

03 Aug 2022
Researchers have designed smart, colour-controllable white light devices from quantum dots – tiny semiconductors just a few billionths of a metre in...

Theoretical ESR spectrum buildup as a function of two-photon detuning δ and drive time τ, for a Rabi frequency of Ω = 3.3 MHz on the central transition.

Physicists get thousands of semiconductor nuclei to do ‘quantum dances’ in unison

22 Feb 2019
A team of Cambridge researchers have found a way to control the sea of nuclei in semiconductor quantum dots so they can operate as a quantum memory...

An image from an experiment in the quantum optics laboratory in Cambridge. Laser light was used to excite individual tiny, artificially constructed atoms known as quantum dots, to create “squeezed” single photons

Scientists "squeeze" light one particle at a time

01 Sep 2015
A team of scientists have measured a bizarre effect in quantum physics, in which individual particles of light are said to have been “squeezed” – an...
