How Do Quantum Algorithms Work?
Imagine you’re trying to find the shortest path between two cities. A classical computer would methodically test each possible route, one by one, until it finds the shortest one. A quantum algorithm, on the other hand, would create a quantum circuit that simultaneously explores all possible routes, instantly collapsing into the shortest one. This is the power of quantum parallelism.
Applications of Quantum Algorithms for Optimization
