GENERALIZATION OF A QUANTUM IMAGINARY TIME EVOLUTION PROCESS AND SIMULATION BY TENSOR NETWORKS

Abstract:

Systems, computer-implemented methods, and computer program products to facilitate generalization of a quantum imaginary time evolution process and simulation by tensor networks are provided. According to an embodiment, a system can comprise a processor that executes computer executable components stored in memory. The computer executable components can comprise a universal component that generalizes a quantum imaginary time evolution process to provide a quantum imaginary time evolution ansatz process. The computer executable components can further comprise a simulation component that applies the quantum imaginary time evolution ansatz process to one or more general multi-body quantum systems.
