Dataset Accompanying: Simultaneous single-qubit driving of semiconductor spin qubits at the fault-tolerant threshold
<p> The promise of quantum information technology hinges on the ability to control large numbers of qubits with high fidelity. Quantum dots define a promising platform due to their compatibility with semiconductor manufacturing. Moreover, high-fidelity operations above 99.9\% have been realized with individual qubits \cite{Yoneda2018,Yang2019a,Hendrickx2021}, though their performance has been limited to 98.67\% when driving two qubits simultaneously \cite{Xue2019}. \textcolor{red}{Here we present single-qubit randomized benchmarking in a two-dimensional array of spin qubits, finding native gate fidelities as high as 99.992(1)\%. Furthermore, we benchmark single qubit gate performance while simultaneously driving two and four qubits. To do this, we develop a novel benchmarking technique called $N$-copy randomized benchmarking, designed for simple experimental implementation, while providing a good estimate of the simultaneous qubit gate fidelity. We find two- and four-copy randomized benchmarking fidelities as high as 99.905(8)\% and 99.34(4)\% respectively. We also find that two-copy benchmarking of next-nearest neighbour pairs can return fidelities within the error margin of their single qubit cases, indicating that cross talk can be highly local in the absence of an exchange interaction.} These characterizations of the single-qubit gate quality and the ability to operate simultaneously are crucial aspects for scaling up germanium based quantum information technology. </p>

A Three‐Dimensional Porous Organic Semiconductor Based on Fully sp2‐Hybridized Graphitic Polymer
<p>Dimensionality plays an important role in the charge transport properties of organic semiconductors. Although three- dimensional semiconductors, such as Si, are common in inorganic materials, imparting electrical conductivity to covalent three- dimensional organic polymers is challenging. Here, we report the synthesis of a three-dimensional π-conjugated porous organic polymer (3D p-POP) using catalyst-free Diels−Alder cycloaddition polymerization followed by acid-promoted aromatization. With a surface area of 801 m<sup>2</sup> g<sup>-1</sup> , full conjugation throughout the carbon backbone, and an electrical conductivity of 6(2) x 10<sup>–4</sup> S cm<sup>–1</sup> upon treatment with I<sub>2</sub> vapor, the 3D p-POP represents the first member of a new class of permanently porous 3D organic semiconductors.</p>

Data from: Convenient fabrication of conjugated polymer semiconductor nanotubes and their application in organic electronics
Organic heterojunction is indispensable in organic electronic devices, such as organic solar cells (OSCs), organic light-emitting diodes (OLEDs) and so on. Fabrication of core-shell nanostructure provides feasible and novel way to prepare organic heterojunction, which is beneficial for miniaturization and integration of organic electronic devices. Fabrication of nanotubes which constitute the core-shell structure in large quantity is the key for the realization of application. In this work, a simple and convenient method to prepare nanotubes utilizing conjugated copolymer of perylene diimide and dithienothiophene (P(PDI-DTT)) was demonstrated. The relationship between preparation condition (solvent atmosphere, solution concentration and pore diameter of templates) and morphology of nanostructure was studied systematically. P(PDI-DTT) nanotubes could be fabricated in regular shape and large quantity by preparing the solution with appropriate concentration and placing Anodic Aluminum Oxide (AAO) template with nanopore diameter of 200 nm in the solvent atmosphere. The tubular structure was confirmed by scanning electron microscope (SEM). P(PDI-DTT) nanotubes exhibited electron mobility of 0.02 cm2V-1s–1 in field effect transistors under ambient condition. Light emitting nanostructures were successfully fabricated by incorporating tetraphenyl ethylene (TPE) into polymer nanotubes.
