Fault-tolerant quantum computing requires high-fidelity quantum gates that are resilient to control errors and device imperfections. Here, we develop energy-optimal control pulses for single-qubit gates that are simultaneously robust against frequency detuning and waveform inhomogeneities while also suppressing leakage...

Classical shadows allow the prediction of many quantum-state properties from measurement data, but their efficiency strongly depends on the underlying measurement ensemble. We introduce selective GHZ measurement (SGM) shadows, which perform Greenberger-Horne-Zeilinger (GHZ)-basis measurements on randomly selected subse...

Simulation-based quantum system inference is introduced, a unified, likelihood-free framework that learns parameter posteriors directly from classical simulation data to reduce data-acquisition requirements in quantum experiments and accelerates parameter inference, providing a practical route to characterizing and imp...

The results show that heuristic GC methods substantially reduce the number of required measurement settings for QST and enable priority-based scheduling that maximizes the information gain per experiment, providing speedups of several orders of magnitude over brute-force methods already for these relatively small quant...
