Professor Andrew Dzurak’s team has had new results opening the path to a quantum data bus for silicon CMOS quantum processor chips published in Nature Communications yesterday. These show that electron spin qubits can be transported between quantum dots while maintaining their spin polarisation (to 99.97%) and spin coherence (to 99.4%) information. The experiments were performed by former postdoc Jun Yoneda and former PhD student Wister Huang, crucial theory was supported by Andre Saraiva and his PhD student Mengke Feng, and all devices were all fabricated at ANFF-NSW.
