Charting a new path to quantum computers with zinc oxide 'quantum dots'

Japanese researchers have taken an important step in the development of quantum computing based on semiconductors. This group has managed to use radio frequency electric charge detection technology in a device based on zinc oxide (ZnO) and to prove the construction of a "double quantum dot" with a very small number of electrons; An achievement that can provide the necessary infrastructure for the development of spin qubits in this material.
