• Abstract: In quantum sideband high harmonic generation (QSHHG), high harmonic generation is perturbed by a bright quantum field resulting in harmonic sidebands, with the intent to transfer non-classical properties from the quantum perturbation to the harmonic sidebands. So far, non-classical features have not been found in QSHHG yet. The closed form theory of QSHHG in atoms and solids developed here answers the question under which conditions non-classical features can be realized. QSHHG results in a multi-mode entanglement between harmonic sideband modes and perturbative quantum mode. A projective measurement on either creates a variety of non-classical states commonly used in quantum information science. This opens a pathway towards quantum engineering high harmonic generation as a short wavelength source for quantum information science.

  We introduce a quantum hardness assumption called the Hamiltonian Phase State (HPS) problem. We show that our assumption is plausibly fully quantum; meaning, it cannot be used to construct one-way functions. We show that our assumption and its variants allow us to efficiently construct many pseudorandom quantum primitives.

  We report on experimental tests of topological defect formation via the one-dimensional transverse-field Ising model. We find that the quantum simulator results can indeed be explained by the KZM for open-system quantum dynamics with phase-flip errors. This implies that the theoretical predictions of the generalized KZM theory, which assumes isolation from the environment, applies beyond its original scope to an open system.
