Quantum computing is an emerging field that leverages and revolutionizes industries by harnessing the principles of quantum mechanics to perform computations far beyond the capabilities of classical computers. Unlike classical computers, which process information in binary form, quantum computers leverage quantum bits or qubits, which can exist in multiple states simultaneously due to superposition and interact through entanglement, allowing for exotically faster computations.
The Principles of Quantum Computing
- Superposition – Qubits can exist in a combination of both 0 and 1 states, allowing quantum computers to perform multiple calculations at once.
- Entanglement – Qubits can be entangled, meaning the state of one qubit is directly related to another, even over vast distances. This enables faster and more secure information processing.
- Quantum Interference – This principle allows quantum algorithms to amplify correct solution while cancelling out incorrect ones, increasing computational efficiency.
Major companies like IBM, Google, Microsoft and startups like IonQ and Rigetti are completion to build more stable and scalable quantum systems.
