The Science Behind Quantum Computing: A Beginner’s Guide
The Science Behind Quantum Computing: A Beginner's Guide Quantum computing represents a revolutionary leap in the world of technology, offering the potential to solve complex problems far beyond the capabilities of traditional computers. At its core, quantum computing leverages the principles of quantum mechanics—a branch of physics that deals with the behavior of particles on the atomic and subatomic levels. How Quantum Computing Differs from Classical Computing Traditional computers use bits as the smallest data unit, which exist in one of two states: 0 or 1 . These bits follow the rules of classical physics. In contrast, quantum computers use qubits (quantum bits). Thanks to a phenomenon called superposition , qubits can exist in both the 0 and 1 states at the same time. This ability to perform multiple calculations simultaneously gives quantum computers their extraordinary potential. In addition to superposition, quantum computers use another unique property known as entangl...
