Symmetry enhanced variational quantum imaginary time evolution
Xiaoyang Wang, Yahui Chai, Maria Demidik +3
The variational quantum imaginary time evolution (VarQITE) algorithm is a near-term method to prepare the ground state and Gibbs state of Hamiltonians. Finding an appropriate param…
Nonperturbative renormalization of asymmetric staple-shaped operators in twisted mass lattice QCD
Constantia Alexandrou, Simone Bacchio, Krzysztof Cichy +8
Staple-shaped Wilson line operators are necessary for the study of transverse momentum-dependent parton distribution functions (TMDPDFs) in lattice QCD and beyond. In this work, we…
Canonical Momenta in Digitized SU(2) Lattice Gauge Theory: Definition and Free Theory
Timo Jakobs, Marco Garofalo, Tobias Hartung +5
Hamiltonian simulations of quantum systems require a finite-dimensional representation of the operators acting on the Hilbert space H. Here we give a prescription for gauge links a…
Computing the Mass Shift of Wilson and Staggered Fermions in the Lattice Schwinger Model with Matrix Product States
Takis Angelides, Lena Funcke, Karl Jansen +1
Simulations of lattice gauge theories with tensor networks and quantum computing have so far mainly focused on staggered fermions. In this paper, we use matrix product states to st…
Exploring the CP-violating Dashen phase in the Schwinger model with tensor networks
Lena Funcke, Karl Jansen, Stefan Kühn
We numerically study the phase structure of the two-flavor Schwinger model with matrix product states, focusing on the (1+1)-dimensional analog of the CP-violating Dashen phase in…
Critical behavior of Ising model by preparing thermal state on quantum computer
Xiaoyang Wang, Xu Feng, Tobias Hartung +2
We simulate the critical behavior of the Ising model utilizing a thermal state prepared using quantum computing techniques. The preparation of the thermal state is based on the var…
