Improved constant factors for qubitized Hamiltonian simulation
Matthew Pocrnic, Danial Motlagh
Quantum signal processing (QSP) serves as the asymptotically optimal technique for Hamiltonian simulation on a quantum computer. By approximating the time evolution operator via th…
Theory and practice of Trotter product formulas for quantum chemistry
Pablo A. M. Casares, William Maxwell, Danial Motlagh +7
Trotter product formulas are a fundamental class of methods for Hamiltonian simulation, particularly attractive due to their low qubit requirements. However, they are often overloo…
Practical Estimation of Trotter Error for Hamiltonian Simulation
William Maxwell, Pablo A. M. Casares, Robert A. Lang +7
Trotter product formulas are a leading approach for Hamiltonian simulation on quantum computers, yet their practical performance has remained difficult to assess due to the challen…
Halving the cost of QROM
Danial Motlagh, Matthew Pocrnic
Table lookup, often referred to as quantum read only memory (QROM), is one of the most widely used subroutines in quantum algorithms, and constitutes the majority share of algorith…
Quantum algorithm for simulating resonant inelastic X-ray scattering in battery materials
Ignacio Loaiza, Alexander Kunitsa, Stepan Fomichev +9
Resonant inelastic X-ray scattering (RIXS) is the workhorse experimental technique for probing the structural degradation of higher-capacity cathode materials. However, the interpr…
Quantum algorithm for simulating non-adiabatic dynamics at metallic surfaces
Robert A. Lang, Paarth Jain, Juan Miguel Arrazola +1
Non-adiabatic dynamics at molecule-metal interfaces govern diverse and technologically important phenomena, from heterogeneous catalysis to dye-sensitized solar energy conversion a…
