Determining probability density functions with adiabatic quantum computing
No full textThe two main approaches to quantum computing are gate-based computation and analog computation, which are polynomially equivalent in terms of complexity, and they are often seen as alternatives to each other. In this work, we present a method for fitting one-dimensional probability distributions as a practical example of how analog and gate-based computation can be used together to perform different tasks within a single algorithm. In particular, we propose a strategy for encoding data within an adiabatic evolution model, which accommodates the fitting of strictly monotonic functions, as it is the cumulative distribution function of a dataset. Subsequently, we use a Trotter-bounded procedure to translate the adiabatic evolution into a quantum circuit in which the evolution time t is identified with the parameters of the circuit. This facilitates computing the probability density as derivative of the cumulative function using parameter shift rules
2D sigma models on noncompact Calabi-Yau manifolds and <math display="inline"><mi mathvariant="script">N</mi><mo>=</mo><mn>2</mn></math> Liouville theory
No full textWe consider a class of two dimensional conformal N=2 supersymmetric U(1) gauge linear sigma models with N fields of charges +1 and N fields of charges -1, whose Higgs branches are noncompact toric Calabi-Yau manifolds of complex dimension 2N-1. We show, starting from large-N approximation, that the Coulomb branch of these models, which opens up at strong coupling, is described by N=2 Liouville theory and then extrapolate it to exact equivalence demanding the central charge of the Liouville theory to be c^=2N-1. Next, we concentrate on mostly physically attractive N=2 and N≥3 cases and find there a perfect agreement of the set of complex moduli on the Calabi-Yau side with the marginal deformations in N=2 Liouville theory, supporting proposed exact equivalence
Total Momentum and Other Noether Charges for Particles Interacting in a Quantum Spacetime
No full textThere has been strong interest in the fate of relativistic symmetries in some quantum spacetimes, partly because of its possible relevance for high-precision experimental tests of relativistic properties. However, the main technical results obtained so far concern the description of suitably deformed relativistic symmetry transformation rules, whereas the properties of the associated Noether charges, which are crucial for the phenomenology, are still poorly understood. Here, we tackle this problem focusing on first-quantized particles described within a Hamiltonian framework and using as a toy model the so-called "spatial kappa-Minkowski noncommutative spacetime", where all the relevant conceptual challenges are present but, as here shown, in technically manageable fashion. We derive the Noether charges, including the much-debated total momentum charges, and we reveal a strong link between the properties of these Noether charges and the structure of the laws of interaction among particles
Panorama of new-physics explanations to the MiniBooNE excess
No full textThe MiniBooNE low-energy excess stands as an unexplained anomaly in short-baseline neutrino oscillation experiments. It has been shown that it can be explained in the context of dark sector models. Here, we provide an overview of the possible new-physics solutions based on electron, photon, and dilepton final states. We systematically discuss the various production mechanisms for dark particles in neutrino-nucleus scattering. Our main result is a comprehensive fit to the MiniBooNE energy spectrum in the parameter space of dark neutrino models, where short-lived heavy neutral leptons are produced in neutrino interactions and decay to e+e- pairs inside the detector. For the first time, other experiments will be able to directly confirm or rule out dark neutrino interpretations of the MiniBooNE low-energy excess
