Quantum dots with confined light holes could have applications in quantum technologies

(Phys.org) —Semiconductor quantum dots are being widely studied for their potential use in future quantum technologies. One of the reasons for their appeal is that they can confine quantum bits such as excitons and spins inside of them. In a new study, researchers have created a quantum dot that contains an exciton in the form of an electron bound to a light hole. The use of a light (as opposed to heavy) hole could enable the quantum dots to have specific advantages for quantum information technologies.
