Machine learning at the quantum lab
The electron spin of individual electrons in quantum dots could serve as the smallest information unit of a quantum computer. Scientists from the Universities of Oxford, Basel and Lancaster have developed an algorithm that can be used to measure quantum dots automatically. Writing in the Nature-family journal npj Quantum Information, they describe how they can speed up this hugely time-consuming process by a factor of four with the help of machine learning. Their approach to the automatic measurement and control of qubits therefore represents a key step toward their large-scale application.
