❓ Frequently Asked Questions
What is a quantum algorithm and how does it differ from a classical algorithm?
Quantum algorithms use quantum bits and phenomena like superposition and entanglement to process information in ways not possible classically, often enabling speedups for specific problems.
What problem does Shor's algorithm solve?
Shor's algorithm factors large integers efficiently on a quantum computer, potentially breaking many classical cryptosystems such as RSA.
What is Grover's algorithm and what kind of problems does it address?
Grover's algorithm searches unsorted databases or solution spaces with a quadratic speedup, performing in roughly the square root of the search size.
Why are superposition and entanglement important for quantum algorithms?
Superposition lets quantum systems represent many possibilities at once, while entanglement creates correlations that enable interference patterns beyond classical capabilities.
Are quantum algorithms always faster than classical ones?
Not always. Speedups depend on the problem and hardware; practical advantages require scalable, fault-tolerant quantum computers and suitable problem structure.
