Benchmarking an 11-qubit quantum computer

Abstract The field of quantum computing has grown from concept to demonstration devices over the past 20 years. Universal quantum computing offers efficiency in approaching problems of scientific and commercial interest, such as factoring large numbers, searching databases, simulating intractable models from quantum physics, and optimizing complex cost functions. Here, we present an 11-qubit fully-connected, programmable quantum computer in a trapped ion system composed of 13 171 Yb + ions. We demonstrate average single-qubit gate fidelities of 99.5 $$\%$$ % , average two-qubit-gate fidelities of 97.5 $$\%$$ % , and SPAM errors of 0.7 $$\%$$ % . To illustrate the capabilities of this universal platform and…
