Global and nonlocal magic of quantum many-body scars
Lukas Ebner, Giovanni Cataldi, Kaidi Xu +2
Nonergodic features of chaotic quantum many-body systems are commonly characterized through local observables, fidelity, and entanglement entropy. Here, using global and nonlocal m…
Observation of glueball excitations and string breaking in a D lattice gauge theory on a trapped-ion quantum computer
Kaidi Xu, Umberto Borla, Kevin Hemery +4
A major goal of the quantum simulation of high-energy physics (HEP) is to probe real-time nonperturbative far-from-equilibrium quantum processes underlying phenomena such as hadron…
Coherent Quantum Evaluation of Collider Amplitudes for Effective Field Theory Constraints
Yacine Haddad, Kaidi Xu, Vincent Croft +2
Precision measurements at electron-positron colliders provide stringent tests of the Standard Model and powerful probes of possible higher-dimensional interactions. We present a hy…
Repulsively Bound Hadrons in a Lattice Gauge Theory
Sayak Guha Roy, Vaibhav Sharma, Kaidi Xu +3
The lattice gauge theory is a paradigmatic model that exhibits gauge-field-mediated-confinement of pairs of particles into mesons, drawing connections to quantum chr…
Role of Plaquette Term in Genuine D String Dynamics on Quantum Simulators
Yizhuo Tian, N. S. Srivatsa, Kaidi Xu +3
With the advent of quantum simulators of D lattice gauge theories (LGTs), a fundamental open question is under what circumstances the observed physics is genuinely D rath…
String Breaking Dynamics and Glueball Formation in a D Lattice Gauge Theory
Kaidi Xu, Umberto Borla, Sergej Moroz +1
With the advent of advanced quantum processors capable of probing lattice gauge theories (LGTs) in higher spatial dimensions, it is crucial to understand string dynamics in such mo…
Suppression of dephasing by qubit motion in superconducting circuits
D. V. Averin, K. Xu, Y. P. Zhong +3
We suggest and demonstrate a protocol which suppresses dephasing due to the low-frequency noise by qubit motion, i.e., transfer of the logical qubit of information in a system of $…
