Implementation of quantum imaginary-time evolution method on NISQ devices by introducing nonlocal approximation
Abstract The imaginary-time evolution method is a well-known approach used for obtaining the ground state in quantum many-body problems on a classical computer. A recently proposed quantum imaginary-time evolution method (QITE) faces problems of deep circuit depth and difficulty in the implementatio...
