A Kernel-Based Density of States Estimator for Quantum Computing
Julio Cesar Siqueira Rocha
The density of states (DoS) encodes the thermodynamic and spectral properties of quantum many-body systems, yet its reconstruction becomes intractable for Hilbert spaces too large…

Unraveling Rodeo Algorithm Through the Zeeman Model
Raphael Fortes Infante Gomes, Julio Cesar Siqueira Rocha, Wallon Anderson Tadaiesky Nogueira +1
We unravel the Rodeo Algorithm to determine the eigenstates and eigenvalues spectrum for a general Hamiltonian considering arbitrary initial states. By presenting a novel methodolo…
