Quantum computer
A quantum computer is a type of computer that uses the principles of quantum mechanics—the physics of very small particles like atoms and electrons—to process information in ways that classical computers cannot.

This ability to be in multiple states at once gives quantum computers their unique power.
Key quantum principles they use
-
Superposition
A qubit can represent multiple values simultaneously.
This means a quantum computer can explore many possibilities at once.
-
Entanglement
Qubits can be linked so that changing one instantly affects the other, even if far apart.
This allows extremely fast coordination between qubits.
-
Interference
Quantum computers can amplify correct answers and cancel wrong ones through wave-like behavior.
