Preparing strongly coupled particle states on quantum computers requires large resources. The study demonstrates a method of using classical sampling coupled with projection operators to compute Minkowski matrix elements without explicitly preparing these states on the quantum computer. This approach was tested on small lattices with a quantum simulator for the 2+1d Z(2) lattice gauge theory.
Preparing strongly coupled particle states on quantum computers requires large resources. In this work, we show how classical sampling coupled with projection operators can be used to compute Minkowski matrix elements without explicitly preparing these states on the quantum computer. We demonstrate this for the 2+1d Z(2) lattice gauge theory on small lattices with a quantum simulator.
