Quantum theory is a fundamental framework in physics that describes the behavior of matter and energy at the smallest scales, where classical physics fails to apply. It introduces concepts like wave-particle duality, quantization, and entanglement, fundamentally altering our understanding of reality and laying the groundwork for technologies like quantum computing.

Classical physics encompasses the principles and theories developed before the advent of quantum mechanics and relativity, primarily focusing on macroscopic phenomena. It includes foundational laws and concepts that describe the motion of bodies, forces, energy, and the properties of matter and waves in a deterministic framework.

Wave-particle duality is a fundamental concept in quantum mechanics that describes how every particle or quantum entity exhibits both wave and particle properties. This duality is exemplified by experiments such as the double-slit experiment, where particles like electrons create interference patterns, a characteristic of waves, yet also behave as discrete particles when observed.

Quantization is the process of converting a continuous range of values into a finite range of discrete values, often used in digital signal processing to approximate analog signals. It introduces quantization error, which is the difference between the actual analog value and the quantized digital value, impacting the precision and accuracy of the representation.

Entanglement is a quantum phenomenon where particles become interconnected such that the state of one instantly influences the state of another, regardless of distance. This non-local interaction challenges classical intuitions about separability and locality, playing a crucial role in quantum computing and quantum cryptography.

Quantum computing leverages the principles of quantum mechanics to process information in ways that classical computers cannot, using qubits that can exist in multiple states simultaneously. This allows for potentially exponential increases in computing power, enabling solutions to complex problems in fields like cryptography, optimization, and materials science.
