Preparing thermal states of frustrated quantum spin systems using 139 qubits
Roland C. Farrell, Yongtao Zhan, Lucas Katschke +3
Finite-temperature properties of strongly correlated quantum matter are central to condensed matter, chemistry, and high-energy physics, yet are often inaccessible to classical met…
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…
Finite-Temperature Dynamical Phase Diagram of the D Quantum Ising Model
Lucas Katschke, Roland C. Farrell, Umberto Borla +2
Mapping finite-temperature dynamical phase diagrams of quantum many-body models is a necessary step towards establishing a framework of far-from-equilibrium quantum many-body unive…
Studying energy-resolved transport with wavepacket dynamics on quantum computers
Melody Lee, Roland C. Farrell
Probing energy-dependent transport in quantum simulators requires preparing states with tunable energy and small energy variance. Existing approaches often study quench dynamics of…
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-…
Universal corrections to the superfluid gap in a cold Fermi gas
Silas R. Beane, Zeno Capatti, Roland C. Farrell
A framework for computing the superfluid gap in an effective field theory (EFT) of fermions interacting via momentum-independent contact forces is developed. The leading universal…
