Tomography of entangling two-qubit logic operations in exchange-coupled donor electron spin qubits
<p>Scalable quantum processors require high-fidelity universal quantum logic operations in a manufacturable physical platform. Donors in silicon provide atomic size, excellent quantum coherence and compatibility with standard semiconductor processing, but no entanglement between donor-bound electron spins has been demonstrated to date. Here we present the experimental demonstration and tomography of universal 1- and 2-qubit gates in a system of two weakly exchange-coupled electrons, bound to single phosphorus donors introduced in silicon by ion implantation. We surprisingly observe that the exchange interaction has no effect on the qubit coherence. We quantify the fidelity of the quantum operations using gate set tomography (GST), and we use the universal gate set to create entangled Bell states of the electrons spins, with fidelity ≈ 93%, and concurrence 0.91 ± 0.08. These results form the necessary basis for scaling up donor-based quantum computers.</p>

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>
