Spring 2025 Colloquia
Title: "Exploring quantum simulation and entanglement dynamics of complex quantum systems with quantum computers"
Abstract: Quantum computers are opening new frontiers in fundamental physics, offering unprecedented opportunities to explore complex quantum systems. In this talk, I will present our recent quantum simulations focused on two key directions: (1) large-scale frustrated quantum spin chains and (2) black hole entanglement dynamics. Using IBM’s superconducting quantum computers, we successfully implemented a Heisenberg spin chain with competing nearest-neighbor and next-nearest neighbor interactions, achieving real-time evolution with up to 100 qubits and accurate expectation value measurements utilizing scalable constant-depth quantum circuits and error mitigation. I will also discuss our quantum simulation of black hole scrambling dynamics conducted with IBM's superconducting quantum computers. We employed randomized measurement and swap-based many-body interference protocols to investigate entanglement entropy dynamics, providing insights into the Page curve and the black hole information puzzle. Finally, our research showcases quantum computers as a nascent but powerful tool for exploring complex quantum systems and beyond.
Title: The Deep Underground Neutrino Experiment (DUNE): An International Experiment for Neutrino Science
Abstract:
DUNE is a future experiment designed to answer two major open questions in neutrino science: What is the neutrino mass ordering (mass hierarchy); and do neutrinos violate CP invariance? In order to answer these questions, DUNE will measure neutrino oscillations over a long baseline utilizing the 1.2 – 2.4 MWatt wide-band neutrino beam from the Long-Baseline Neutrino Facility (LBNF) at Fermilab, a 40 kTon fiducial volume liquid argon time-projection chamber far detector located 1300 km from the beam source in the Sanford Underground Research Facility (SURF) in Lead, South Dakota, and a near detector system at the source. This talk will review recent results from neutrino oscillation measurements and present the design of DUNE along with its expected physics sensitivities.
In addition to this summary, I will present details of two specific DUNE projects which Wichita State University is participating in: the design and analysis of the DUNE near detector system; and the development of core computing software, including a new data processing framework.
