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…
Qudit Implementation of the Rodeo Algorithm for Quantum Spectral Filtering
Julio Cesar Siqueira Rocha, Rodrigo Alves Dias
Qudits, the multi-level generalization of qubits, provide a natural extension of the binary paradigm in quantum computation and offer new opportunities to enhance algorithmic perfo…
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…
Estimating the Number of States via the Rodeo Algorithm for Quantum Computation
Julio Cesar Siqueira Rocha, Raphael Fortes Infante Gomes, Wallon Anderson Tadaiesky Nogueira +1
In the realm of statistical physics, the number of states in which a system can be realized with a given energy is a key concept that bridges the microscopic and macroscopic descri…
