Physics forms the basis of quantum computing, as it provides the fundamental principles and concepts necessary to comprehend the behaviour of quantum systems. To navigate the world of quantum computing effectively, a solid understanding of key principles in quantum physics is crucial.
At the core of quantum physics lies the principle of superposition. Unlike classical systems that exist in definite states, quantum systems can exist in multiple states simultaneously. This principle allows qubits, the building blocks of quantum computers, to represent and process information in a fundamentally different way than classical bits. Understanding superposition is vital for grasping the power and potential of quantum computing.
Entanglement is another fundamental concept in quantum physics that plays a crucial role in quantum computing. When two or more qubits become entangled, their states become intertwined, resulting in a unique correlation that persists even when the qubits are physically separated. Entanglement enables quantum computers to perform parallel computations and exhibit exponential computational power compared to classical computers.
Quantum measurement is an essential aspect of quantum physics. Measurement outcomes in quantum systems are probabilistic in nature, and they reveal information about the state of a quantum system.
