Quantum Annealing

1. Introduction

Quantum annealing is a quantum computing method used to solve optimization problems by leveraging quantum mechanics principles. It is particularly effective for finding the global minimum of a given objective function.

2. Key Concepts

• **Quantum Superposition**: The ability of quantum systems to be in multiple states at once.
• **Quantum Tunneling**: A phenomenon where particles pass through potential barriers, allowing the system to escape local minima.
• **Ising Model**: A mathematical model used to represent spin systems, often used in quantum annealing.

3. Quantum Annealing Process

The quantum annealing process can be summarized in the following steps:

1. Define the optimization problem.
2. Map the problem onto a Hamiltonian.
3. Prepare the initial state of the quantum system.
4. Evolve the system using quantum annealing.
5. Measure the final state to obtain the solution.
