What is Quantum Computing?
/ˈkwɒntəm kəmˈpjuːtɪŋ/
Quantum computing uses the principles of quantum mechanics — superposition and entanglement — to process information in fundamentally different ways than classical computers, solving certain problems exponentially faster.

Everyday Example
A classical computer solves a maze by trying one path at a time. A quantum computer can explore all possible paths simultaneously, finding the solution in a fraction of the time.
publicReal-World Application
“Google claimed "quantum supremacy" in 2019 when its quantum processor solved a calculation in 200 seconds that would take the world's best classical supercomputer 10,000 years.”

Did you know?
Richard Feynman first proposed the idea of quantum computing in 1982. Practical quantum computers only became reality in the 2010s.

Key Insight
Quantum computers are not "faster computers" — they are fundamentally different. They will not replace laptops; they will solve specific problems (cryptography, drug discovery, logistics) that classical computers cannot.
