Researchers developed the first device that can detect single-electron events in a self-assembled quantum dot in real time. The device detects the single-electron tunneling events of one quantum dot as changes in the current produced by a second quantum dot in close proximity. This device allows single-electron events in quantum dots to be investigated, which is beneficial for the development of photonic devices and quantum computing.
