What is Quantum Annealing?
Quantum annealing is a fascinating concept in the world of quantum computing. It’s a method used to find the global minimum of a given objective function over a given set of candidate solutions. This approach leverages quantum mechanics to solve optimization problems more efficiently than classical methods.
- 01
Quantum annealing uses quantum bits, or qubits, which can exist in multiple states simultaneously, unlike classical bits that are either 0 or 1.
- 02
The process involves gradually transforming a simple quantum system into a more complex one, allowing it to explore many possible solutions at once.
- 03
Quantum annealing is particularly effective for solving combinatorial optimization problems, where the goal is to find the best solution from a finite set of possibilities.
