Development of an Efficient Method for Computing the Green's Functions of Large-Scale Electronic Systems ~ A Steady Step Toward the Application of Quantum Computers to Strongly-Correlated Electrons ~

QunaSys, in joint research with Fujitsu, has developed a method to efficiently compute "Green’s functions" in large-scale electronic systems using quantum computers. This research result is a steady step toward the realistic application of quantum computers to materials science. The computation of large-scale quantum many-body systems is one of the most promising areas where quantum computers can realize the computational speedup over classical computers.
