Quantum algorithms are a set of algorithms that run on quantum computers. These algorithms are designed to take advantage of the unique properties of quantum bits, or qubits, to solve certain problems much faster than classical algorithms.
Key Quantum Algorithms
Shor's Algorithm
- Shor's algorithm is a quantum algorithm for factoring large numbers. It is believed to be one of the most significant quantum algorithms, as it has the potential to break many of the public-key cryptosystems that are currently in use.

Grover's Algorithm
- Grover's algorithm is a quantum algorithm for searching an unsorted database of N items in O(√N) time, or O(N) with a single qubit. This is a significant improvement over the best possible classical algorithm, which requires O(N) time.
