    "abstract": "Cluster states, a special type of highly entangled states, are a universal\nresource for measurement-based quantum computation. Here, we propose an\nefficient one-step generation scheme for cluster states in semiconductor\nquantum dot molecules, where qubits are encoded on singlet and triplet state of\ntwo coupled quantum dots. By applying a collective electrical field or\nsimultaneously adjusting interdot bias voltages of all double-dot molecule, we\nget a switchable Ising-like interaction between any two adjacent quantum\nmolecule qubits. The initialization, the single qubit measurement, and the\nexperimental parameters are discussed, which shows the large cluster state\npreparation and one-way quantum computation implementable in semiconductor\nquantum dots with the present techniques.",
