A Reconstruction of Michelson Interference from On--Off Detection Statistics
Kim Myung-Whun
This paper reconstructs the Michelson interference phenomenon based solely on the binary (on-off) statistics of a single-photon counter and macroscopic path-difference data, withou…
Local universality of non-local quantum resources in rotationally invariant scattering
Silas R. Beane, Roland C. Farrell
Elastic scattering can generate entanglement and non-local magic between the spins of the two outgoing particles. The amount of entanglement and magic produced is encoded in the S-…
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…
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…
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…
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-…
High Energy Physics from Low Energy Physics
Roland C. Farrell
The separation between physics at low and high energies is essential for physics to have any utility; the details of quantum gravity are not necessary to calculate the trajectory o…
Steps Toward Quantum Simulations of Hadronization and Energy-Loss in Dense Matter
Roland C. Farrell, Marc Illa, Martin J. Savage
A framework for simulating the real-time dynamics of composite particles in a simple model of dense matter that is amenable to quantum computers is developed. As a demonstration, w…
Quantum Simulations of Hadron Dynamics in the Schwinger Model using 112 Qubits
Roland C. Farrell, Marc Illa, Anthony N. Ciavarella +1
Hadron wavepackets are prepared and time evolved in the Schwinger model using 112 qubits of IBM's 133-qubit Heron quantum computer ibm_torino. The initialization of the hadron wave…
Scalable Circuits for Preparing Ground States on Digital Quantum Computers: The Schwinger Model Vacuum on 100 Qubits
Roland C. Farrell, Marc Illa, Anthony N. Ciavarella +1
The vacuum of the lattice Schwinger model is prepared on up to 100 qubits of IBM's Eagle-processor quantum computers. A new algorithm to prepare the ground state of a gapped transl…
Preparations for Quantum Simulations of Quantum Chromodynamics in 1+1 Dimensions: (II) Single-Baryon -Decay in Real Time
Roland C. Farrell, Ivan A. Chernyshev, Sarah J. M. Powell +3
A framework for quantum simulations of real-time weak decays of hadrons and nuclei in a 2-flavor lattice theory in one spatial dimension is presented. A single generation of the St…
