Preparation of initial states with open and periodic boundary conditions on quantum devices using matrix product states
Yibin Guo, Manuel Schneider, Takis Angelides +3
We present a framework for preparing quantum states from matrix product states (MPS) with open and periodic boundary conditions on quantum devices. The MPS tensors are mapped to un…
Scalable Quantum Algorithm for Meson Scattering in a Lattice Gauge Theory
Yahui Chai, Yibin Guo, Stefan Kühn
Scattering processes are fundamental for understanding the structure of matter, yet simulating their real-time dynamics remains challenging for classical computers. Quantum computi…
Meson thermalization with a hot medium in the open Schwinger model
Takis Angelides, Yibin Guo, Karl Jansen +2
Quantum field theories treated as open quantum systems provide a crucial framework for studying realistic experimental scenarios, such as quarkonia traversing the quark-gluon plasm…
Imaginary Hamiltonian variational ansatz for combinatorial optimization problems
Xiaoyang Wang, Yahui Chai, Xu Feng +3
Obtaining exact solutions to combinatorial optimization problems using classical computing is computationally expensive. The current tenet in the field is that quantum computers ca…
Simulating matrix models with tensor networks
Enrico M. Brehm, Yibin Guo, Karl Jansen +1
Matrix models, as quantum mechanical systems without explicit spatial dependence, provide valuable insights into higher-dimensional gauge and gravitational theories, especially wit…
