A Hybrid Classical-Quantum Annealing Algorithm for the TSP
Siwei Hu, Victor Lopata, Salvatore Sinno +2
Hybrid quantum-classical algorithms can help mitigating the physical limitations of current quantum devices, particularly the low qubit count and the reduced topological connectivi…
Verification of Quantum Circuits through Barrier Certificates using a Scenario Approach
Siwei Hu, Victor Lopata, Sadegh Soudjani +1
In recent years, various techniques have been explored for the verification of quantum circuits, including the use of barrier certificates, mathematical tools capable of demonstrat…
Strange-antistrange and charm-anticharm asymmetries of pion in 't Hooft model
Mingliang Zhu, Siwei Hu, Yu Jia +2
As a sequel of our preceding work [S. Hu et al., Phys. Rev. D 108 (2023) 9, 094040], we investigate the strange-antistrange and charm-anticharm asymmetries in the parton distributi…
Light quark mass dependence of nucleon mass to two-loop order
Long-Bin Chen, Siwei Hu, Yu Jia +1
We investigate the nucleon self energy through the sixth chiral order in the covariant chiral perturbation theory (PT) in the single baryon sector. The validity of the e…
Next-to-leading-order QCD corrections to nucleon Dirac form factors
Long-Bin Chen, Wen Chen, Feng Feng +2
The leading-order perturbative QCD (pQCD) predictions to nucleon electromagnetic form factors were first made in late 70s. In this Letter for the first time we accomplish the calcu…
Parton distribution of intrinsic charm in two dimensional QCD
Siwei Hu, Yu Jia, Zhewen Mo +2
We present a detailed investigation on the intrinsic charm content in a light meson within the 't Hooft model, namely, the two-dimensional QCD in large limit. The intrinsic c…
