Quantum computing is an area of computing focused on developing computer technology based on the principles of quantum theory. Quantum theory explains the behavior of energy and material on the atomic and subatomic levels.
In contrast to classical computing, which uses bits as the smallest unit of information (either 0 or 1), quantum computing uses quantum bits or qubits. A qubit can represent both 0 and 1 simultaneously, thanks to the principles of superposition.
Another key principle is entanglement, which allows qubits that are entangled to be correlated with each other even across large distances. These principles enable quantum computers to solve certain complex problems much faster than classical computers.
Quantum computing has the potential to revolutionize fields such as cryptography, material science, pharmaceuticals, and artificial intelligence by providing computational power far beyond the reach of today's classical computers.
