Quantum Markov Chain Monte Carlo for Cosmological Functions
Giuseppe Sarracino, Vincenzo Fabrizio Cardone, Roberto Scaramella +14
We present an implementation of Quantum Computing for a Markov Chain Monte Carlo method with an application to cosmological functions, to derive posterior distributions from cosmol…
The Application of Quantum Fourier Transform in Cosmic Microwave Background Data Analysis
Farida Farsian, Tiziana Trombetti, Carlo Burigana +11
The Cosmic Microwave Background (CMB) data analysis and the map-making process rely heavily on the use of spherical harmonics. For suitable pixelizations of the sphere, the (forwar…
Numerical limits in the integration of Vlasov-Poisson equation for Cold Dark Matter
Luca Cappelli, Giuseppe Murante, Stefano Borgani +12
The Vlasov-Poisson systems of equations (VP) describes the evolution of a distribution of collisionless particles under the effect of a collective-field potential. VP is at the bas…
Benchmarking Quantum Convolutional Neural Networks for Signal Classification in Simulated Gamma-Ray Burst Detection
Farida Farsian, Nicolò Parmiggiani, Alessandro Rizzo +12
This study evaluates the use of Quantum Convolutional Neural Networks (QCNNs) for identifying signals resembling Gamma-Ray Bursts (GRBs) within simulated astrophysical datasets in…
Euclid preparation. 3-dimensional galaxy clustering in configuration space. Part I. 2-point correlation function estimation
Euclid Collaboration, S. de la Torre, F. Marulli +297
The 2-point correlation function of the galaxy spatial distribution is a major cosmological observable that enables constraints on the dynamics and geometry of the Universe. The Eu…
