Quantum simulation of quantum field theory in the light-front formulation
@article{Kreshchuk2022QuantumSO, title={Quantum simulation of quantum field theory in the light-front formulation}, author={Michael Kreshchuk and William M. Kirby and Gary R. Goldstein and H. Beauchemin and Peter J. Love}, journal={Physical Review A}, year={2022} }
We develop quantum simulation algorithms based on the light-front formulation of relativistic quantum field theories. We analyze a simple theory in $1+1D$ and show how to compute the analogues of parton distribution functions of composite particles in this theory. Upon quantizing the system in light-front coordinates, the Hamiltonian becomes block diagonal. Each block approximates the Fock space with a certain harmonic resolution $K$, where the light-front momentum is discretized in $K$ steps…
