However, some challenges have to be overcome to find more suitable and diverse control parameters. We propose a promising and generalizable average-fidelity-based machine-learning-inspired method to optimize the control parameters, in which a neural network with periodic feature enhancement is used as an ansatz. In the implementation of a single-qubit gate by cat-state nonadiabatic geometric quantum computation via reverse engineering, compared with the control parameters in the simple form of a trigonometric function, our approach can yield significantly higher-fidelity (>99.99%) phase gates, such as the π/8 gate (T gate) . Single-qubit gates are robust against systematic noise, additive white Gaussian noise, and decoherence. We numerically demonstrate that the neural network possesses the ability to expand the model space. With the help of our optimization, we provide a feasible way to implement cascaded multiqubit gates with high quality in a bosonic system. Therefore, the machine-learning-inspired method may be feasible in quantum optimal control of nonadiabatic geometric quantum computation.  \nDOI: 10.1103/PhysRevA.108.032616  \nI. INTRODUCTION  \nMultiqubit gates are widely used in quantum circuits [1–3], quantum error correction [4–6], and other fields [7–10] . Single-shot multiqubit gates [11–13] specify quantum circuits that evolute in a well-controlled, uninterrupted, and continuous-time way to implement the quantum computation [14] . Compared to the cascaded gates, single-shot multiqubit gates can greatly reduce the circuit depth and shorten the implementation time, thus suppressing decoherence [15, 16] . However, the single-shot method is difficult to realize in experiments owing to the restricted conditions of simultaneously manipulating multiple physical systems and building complex couplings.  \nOne of the ways to mitigate the above difficulty is the application of single- and two-qubit gates to equivalently implement the function of multiqubit gates [17–19], and the  \n*[xia-208@163.com](xia-208@163.com)[ ](xia-208@163.com)†[a.m.oles@fkf.mpi.de](a.m.oles@fkf.mpi.de)[ ](a.m.oles@fkf.mpi.de)‡[wlyou@nuaa.edu.cn](wlyou@nuaa.edu.cn)  \nPublished by the American Physical Society under the terms of the Creative Commons Attribution 4 .0 International license.

Although the decomposition method loses the upper hand in terms of the circuit depth and the implementation time, it has a wider scope of application due to direct execution on the quantum processing unit, namely, the brain of a quantum computer [21] . The realization of the synthetic gates depends on the universal single-qubit gates and a two-qubit entangling gate with high fidelity [16] .
