From tensors to qubits
Yannick Meurice, Alexei Bazavov, Patrick Dreher +6
We discuss recent progress in Tensor Lattice Field Theory and economical, symmetry preserving, truncations suitable for quantum computations or simulations. We focus on spin and ga…
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…
Benchmarking quantum computers for real-time evolution of a field theory with error mitigation
Erik Gustafson, Patrick Dreher, Zheyue Hang +1
Quantum computers open the possibility of performing real-time calculations for quantum field theory scattering processes. We propose to use an index averaging the absolute value o…
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…
Insight into nucleon structure from generalized parton distributions
LHPC Collaboration, SESAM Collaboration, J. W. Negele +11
The lowest three moments of generalized parton distributions are calculated in full QCD and provide new insight into the behavior of nucleon electromagnetic form factors, the origi…
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…
Physics development of web-based tools for use in hardware clusters doing lattice physics
P. Dreher, W. Akers, J. Chen +2
Jefferson Lab and MIT are developing a set of web-based tools within the Lattice Hadron Physics Collaboration to allow lattice QCD theorists to treat the computational facilities l…
