New method optimizes variational quantum circuits using data alone

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a data-informed method for selecting variational quantum circuits (VQC), eliminating the need for extensive training of numerous candidates. This approach uses three rules based on a dataset's Fourier coefficients and quantum Fisher information matrix to determine the optimal ansatz and depth. For the Madelon dataset, this method prescribed a 239-parameter classifier with 78.5% test accuracy, achieved without traditional grid search, and ablations confirmed the effectiveness of the predicted circuit components.

    Data informed Ansatz Selection for Variational Quantum Circuits

    Choosing a variational quantum circuit (VQC) usually means searching over ansatze and depths, and training each candidate. We give three rules that fix these choices from the data and the gate set alone, before any training. First, a circuit without entangling gates has a rank-on…
