Real-time quantum calculations of phase shifts using wave packet time delays
Erik Gustafson, Yingyue Zhu, Patrick Dreher +2
We present a method to extract the phase shift of a scattering process using the real-time evolution in the early and intermediate stages of the collision in order to estimate the…
Solving Multi-Coloring Combinatorial Optimization Problems Using Hybrid Quantum Algorithms
Young-Hyun Oh, Hamed Mohammadbagherpoor, Patrick Dreher +3
The design of a good algorithm to solve NP-hard combinatorial approximation problems requires specific domain knowledge about the problems and often needs a trial-and-error problem…
An Improved Implementation Approach for Quantum Phase Estimation on Quantum Computers
Hamed Mohammadbagherpoor, Young-Hyun Oh, Patrick Dreher +3
Quantum phase estimation (QPE) is one of the core algorithms for quantum computing. It has been extensively studied and applied in a variety of quantum applications such as the Sho…
Challenges Implementing non-Abelian SU(2) Quantum Chromodynamics Gauge Links On a Universal Quantum Computer
Patrick Dreher
The traditional approach for studying the physics of the strong interactions employs a basic computational construct originally proposed by Wilson in the 1970s. Over the years addi…
Insight into nucleon structure from lattice calculations of moments of parton and generalized parton distributions
J. W. Negele, R. C. Brower, P. Dreher +10
This talk presents recent calculations in full QCD of the lowest three moments of generalized parton distributions and the insight they provide into the behavior of nucleon electro…
Moments of nucleon spin-dependent generalized parton distributions
W. Schroers, R. C. Brower, P. Dreher +10
We present a lattice measurement of the first two moments of the spin-dependent GPD H-tilde(x,xi,t). From these we obtain the axial coupling constant and the second moment of the s…
