Key concepts include qubits, superposition, and entanglement, which form the foundation for understanding how quantum algorithms work. Quantum hardware is crucial in the realisation of these concepts.
Quantum Mechanics and Quantum Theory
Quantum mechanics describes the behaviour of matter and energy at the smallest scales. This branch of physics reveals that particles can exist in multiple states simultaneously, influenced by observers. Quantum theory provides a framework for understanding phenomena such as decoherence and how they affect quantum systems.
In computing, quantum mechanics dismantles classical assumptions, allowing situations where particles like electrons exhibit wave-particle duality. This principle is essential for developing quantum chips that harness these unique properties, leading to superior processing capabilities compared to classical computers.
