Computational Methods for Quantum Simulation of Quantum Annealing
Computational methods for quantum simulation of quantum annealing involve using classical computers to simulate quantum systems undergoing quantum annealing. This approach is motivated by the difficulty of building large-scale quantum computers and the need for efficient optimization algorithms for complex problems.
The core idea behind computational methods for quantum simulation is to approximate the dynamics of a quantum system by solving a corresponding classical problem. This is achieved by discretizing the quantum system’s state space and representing the quantum operators as matrices. The time evolution of the quantum system can then be simulated by repeatedly applying these matrix operators to the state vector.
One widely used approach for quantum simulation of quantum annealing is the Monte Carlo method. This method involves sampling from the Boltzmann distribution of the quantum system and performing random updates to the system’s state. By iteratively applying these updates, the system can be gradually annealed from an initial high-energy state to a low-energy state, approximating the behavior of quantum anneal… Read full answer
