Professor Winfried Hensinger is head of a team that has published an open-access paper in the Science Advances journal. He is quoted as saying: “For many years, people said that it was completely impossible to construct an actual quantum computer. With our work we have not only shown that it can be done but now we are delivering a nuts-and-bolts construction plan to build an actual large-scale machine.”
The design involves multiple trapped ion-based scalable quantum computing modules with an architecture based on long-wavelength radiation quantum gates. Hensinger’s team say modules could be built using silicon microfabrication techniques that are within reach of current technology. A high-threshold surface error correction code can be implemented in the architecture to execute fault-tolerant operations.
