👉 Forward computing, also known as evaluation, is a fundamental process in quantum computing where a quantum algorithm iteratively applies a sequence of quantum gates to an initial quantum state, transforming it into a final state that encodes the solution to the problem at hand. Unlike classical computing, where operations are typically performed sequentially or in parallel, forward computing leverages the superposition and entanglement properties of qubits to perform multiple computations simultaneously. This process involves repeatedly measuring the state of qubits after each gate application, collapsing the superposition to a definite outcome, and using these outcomes to refine the computation until the desired result is obtained. This iterative nature of forward computing is crucial for executing quantum algorithms efficiently, such as Shor's algorithm for factoring large numbers or Grover's search algorithm for unstructured database searches.
