What Is a Quantum Annealers?

Quantum annealing is a metaheuristic for finding the global minimum of a given objective function over a given set of candidate solutions, by a process using quantum fluctuations.

How does a quantum Annealer work?

D-Wave's systems work through a process called quantum annealing. This begins by placing a system's qubits in an absolute energy minimum. From there, the hardware gently alters the configuration of the system so that its energy landscape reflects the problem that needs to be solved.

How does a quantum algorithm work?

In quantum computing, a quantum algorithm is an algorithm which runs on a realistic model of quantum computation, the most commonly used model being the quantum circuit model of computation. ... Grover's algorithm runs quadratically faster than the best possible classical algorithm for the same task, a linear search.
