A capacitively shunted double-transmon coupler enables a 99.92% fidelity parametrically driven iSWAP gate at zero flux between detuned transmons with minimal residual ZZ interaction.
Block-product paired non-Gaussian fermionic states allow efficient classical additive-error approximation of transition amplitudes, overlaps, and high-weight correlators under free-fermionic dynamics using multivariate Pfaffian polynomials.
A digital quantum processor simulates the 1D Fermi-Hubbard model on up to 120 qubits, observing spin-charge separation and achieving quantitative agreement with TDVP while running up to 3000 times faster in wall-clock time for long evolutions.
Structured state preparation in QCQMC improves energy accuracy over pure variational methods across molecular, condensed-matter, nuclear, and graph problems.
SNT merges SV and PEC for subspace-tailored error mitigation in Trotterized FHM simulations, mapping out optimal combinations by hardware quality and shot budget while quantifying when noisy devices could surpass classical methods.
NISQ quantum simulation of spin-wave spectra in 2D chromium tri-halide magnets achieves agreement with classical benchmarks at quasi-constant wall-time scaling.
