Document Type and Number:
WIPO Patent Application WO/2022/252102
Kind Code:
A1
Abstract:
Provided in the present disclosure is a Schrodinger-Heisenberg variational quantum ground state solving method, comprising: constructing a first Hamiltonian corresponding to a problem to be solved; initializing a parameter of a real Schrodinger line, so as to obtain a first parameter value; initializing a parameter of a virtual Heisenberg line, so as to obtain a second parameter value; generating a corresponding quantum state by means of a quantum computer and according to the first parameter value corresponding to the current real Schrodinger line; determining a corresponding second Hamiltonian by means of the computer and according to the second parameter value corresponding to the current virtual Heisenberg line; according to a Pauli term corresponding to the second Hamiltonian, selecting different basis vectors to perform repeat measurement, and calculating an objective function; and optimizing the objective function, updating the first parameter value to obtain a third parameter value, and updating the second parameter value to obtain a fourth parameter value.
