Scattering phase shift in quantum mechanics on quantum computers: non-Hermitian systems and imaginary-time simulations
Peng Guo, Paul LeVan, Frank X. Lee +1
To overcome the fast oscillatory behavior of correlation functions for extracting scattering phase shift in real-time quantum simulations encountered in Ref.\cite{Guo:2026qkx}, we…
Scattering phase shift in quantum mechanics on quantum computers
Peng Guo, Paul LeVan, Frank X. Lee +1
We investigate the feasibility of extracting infinite volume scattering phase shift on quantum computers in a simple one-dimensional quantum mechanical model, using the formalism e…
Toward extracting scattering phase shift from integrated correlation functions on quantum computers
Peng Guo
Based on a established relation in Refs.~\cite{Guo:2023ecc,Guo:2024zal,Guo:2024pvt} that relates the integrated correlation functions for a trapped system to the infinite volume sc…
Bloch oscillation with a diatomic tight-binding model on quantum computers
Peng Guo, Jaime Park, Frank X. Lee
We aim to explore a more efficient way to simulate few-body dynamics on quantum computers. Instead of mapping the second quantization of the system Hamiltonian to qubit Pauli gates…
