Quantum gates are the basic operations used to manipulate qubits in a quantum computer. They are the quantum equivalent of classical logic gates such as AND, OR, and NOT, but quantum gates behave very differently because they operate on quantum states instead of simple binary…

Quantum measurement is the process of extracting classical information from a quantum system. When a qubit is measured, its quantum state collapses and produces a definite classical result — either 0 or 1. Before measurement, the qubit may exist in a superposition containing multiple possible…

Entanglement is one of the most unusual and important phenomena in quantum computing. It occurs when two or more qubits become linked together so that their quantum states are correlated, even when separated by large distances. When one entangled qubit is measured, the state of…

Superposition is one of the core principles behind quantum computing. It allows a qubit to exist in a combination of both 0 and 1 simultaneously instead of being restricted to a single state like a classical bit. This behavior is one of the main reasons…

A qubit is the basic unit of information in quantum computing. In classical computing, a bit can only exist in one of two states: 0 or 1. A qubit behaves differently. Because of quantum mechanics, it can exist in a combination of both states at…
