Making Quantum Light with Quantum Dots

This animation explores how we can use semiconductor "quantum dots" to create quantum light for applications in quantum communications, computing and sensing. A quantum dot is a nano-scale defect in a semiconductor that confines single charge particles (electrons). This video shows how we make quantum dots and how we can use them as a source of single particles of light (photons) for quantum technologies. At the University of Sheffield, we are using these techniques to produce nano-photonic semiconductor chips to power the next generation of optical quantum technologies.
