Spin-projection for quantum computation: A low-depth approach to strong correlation
Although spin is a core property in fermionic systems, its symmetry can be easily violated in a variational simulation, especially when strong correlation plays a vital role therein. In this study, we will demonstrate that the broken spin symmetry can be restored exactly in a quantum computer, with...
