Simulation of Collective Neutrino Oscillations on a Quantum Computer
Benjamin Hall, Alessandro Roggero, Alessandro Baroni +1
In astrophysical scenarios with large neutrino density, like supernovae and the early universe, the presence of neutrino-neutrino interactions can give rise to collective flavor os…
Preparation of excited states for nuclear dynamics on a quantum computer
Alessandro Roggero, Chenyi Gu, Alessandro Baroni +1
We study two different methods to prepare excited states on a quantum computer, a key initial step to study dynamics within linear response theory. The first method uses unitary ev…
Exact representations of many body interactions with RBM neural networks
Ermal Rrapaj, Alessandro Roggero
Restricted Boltzmann Machines (RBM) are simple statistical models defined on a bipartite graph which have been successfully used in studying more complicated many-body systems, bot…
Spectral density estimation with the Gaussian Integral Transform
Alessandro Roggero
The spectral density operator plays a central role in linear response theory as its expectation value, the dynamical response function, can be used to compu…
Quantum Computing for Neutrino-nucleus Scattering
Alessandro Roggero, Andy C. Y. Li, Joseph Carlson +2
Neutrino-nucleus cross section uncertainties are expected to be a dominant systematic in future accelerator neutrino experiments. The cross sections are determined by the linear re…
Short-depth circuits for efficient expectation value estimation
Alessandro Roggero, Alessandro Baroni
The evaluation of expectation values for some pure state and Hermitian operator is of central importance in a variety of quantum algorithms. Near optima…
