Fermionic mean-field dynamics for spin systems beyond free fermions
Rishab Dutta, Marc Illa, Niranjan Govind +1
We introduce the fermionized time-dependent Hartree-Fock (fTDHF), a real-time quantum dynamics method for spin-1/2 Hamiltonians following their mapping to fermions via the Jordan-W…
A Framework for Quantum Simulations of Energy-Loss and Hadronization in Non-Abelian Gauge Theories: SU(2) Lattice Gauge Theory in 1+1D
Zhiyao Li, Marc Illa, Martin J. Savage
Simulations of energy loss and hadronization are essential for understanding a range of phenomena in non-equilibrium strongly-interacting matter. We establish a framework for perfo…
Pathfinding Quantum Simulations of Neutrinoless Double-Beta Decay
Ivan A. Chernyshev, Roland C. Farrell, Marc Illa +10
We present results from co-designed quantum simulations of the neutrinoless double-beta decay of a simple nucleus in 1+1D quantum chromodynamics using IonQ's Forte-generation trapp…
Excited-state uncertainties in lattice-QCD calculations of hadron masses and scattering phase shifts
William Detmold, Anthony V. Grebe, Daniel C. Hackett +4
Lattice QCD has historically produced energy results interpretable as either estimates relying on implicit assumptions about asymptotic behavior or one-sided upper bounds. New Lanc…
Excited-state uncertainties in lattice-QCD calculations of multi-hadron systems
William Detmold, Anthony V. Grebe, Daniel C. Hackett +4
Excited-state effects lead to hard-to-quantify systematic uncertainties in lattice quantum chromodynamics (LQCD) spectroscopy calculations when computationally accessible imaginary…
Digital quantum simulations of scattering in quantum field theories using W states
Roland C. Farrell, Nikita A. Zemlevskiy, Marc Illa +1
High-energy particle collisions can convert energy into matter through the inelastic production of new particles. Quantum computers are an ideal platform for simulating the out-of-…
