Quantum Operations and Quantum Algorithms
Quantum operations are collections of quantum gates that are applied to qubits in order to carry out particular calculations. In order to make use of quantum parallelism and entanglement, quantum algorithms, including Grover's algorithm for database search and Shor's algorithm for factoring huge numbers, are built utilizing quantum gates and operations. First, we can talk about Grover's algorithm. Its purpose is to essentially search for an item in a disordered list, fueled by amplitude amplification, which iteratively rotates the vector of the quantum state. This directional rotation is usually towards the |a> axis, which is a horizontal crystallographic axis. This algorithm is incredibly effective, only less used than Shor's algorithm. Shor's algorithm is used to factor large numbers, sometimes not even being able to be stored in large variables in classical computers, given most only being 64 or 32-bit variables. It can find the prime factors of an integer, in exponential time, being far better than linear. This process is rather advanced, but to keep it short, it uses two different registers, which are collections of qubits, to dynamically process things.
