Nonlinear Spectroscopy via Generalized Quantum Phase Estimation
Ignacio Loaiza, Danial Motlagh, Kasra Hejazi +3
Response theory has a successful history of connecting experimental observations with theoretical predictions. Of particular interest is the optical response of matter, from which…
Better product formulas for quantum phase estimation
Kasra Hejazi, Jay Soni, Modjtaba Shokrian Zini +1
Quantum phase estimation requires simulating the evolution of the Hamiltonian, for which product formulas are attractive due to their smaller qubit cost and ease of implementation.…
Simulating X-ray absorption spectroscopy of battery materials on a quantum computer
Stepan Fomichev, Kasra Hejazi, Ignacio Loaiza +5
X-ray absorption spectroscopy is a crucial experimental technique for elucidating the mechanisms of structural degradation in battery materials. However, extracting information fro…
Better bounds for low-energy product formulas
Kasra Hejazi, Modjtaba Shokrian Zini, Juan Miguel Arrazola
Product formulas are one of the main approaches for quantum simulation of the Hamiltonian dynamics of a quantum system. Their implementation cost is computed based on error bounds…
Initial state preparation for quantum chemistry on quantum computers
Stepan Fomichev, Kasra Hejazi, Modjtaba Shokrian Zini +8
Quantum algorithms for ground-state energy estimation of chemical systems require a high-quality initial state. However, initial state preparation is commonly either neglected enti…
