Quantum entanglement is a phenomenon where two or more particles become linked in such a way that they share the same fate, regardless of the distance between them. Measuring the property of one entangled particle instantly influences the property of the other. This 'spooky action at a distance' is a core concept in quantum mechanics and is vital for quantum computing and communication.
Photons are elementary particles that are quanta of the electromagnetic field, including light and all other forms of electromagnetic radiation. They are massless, travel at the speed of light in a vacuum, and carry energy and momentum. Photons are fundamental to understanding light and its interactions with matter, playing a key role in quantum optics.
Quantum computing uses principles of quantum mechanics, such as superposition and entanglement, to perform calculations. Unlike classical computers that use bits (0 or 1), quantum computers use qubits, which can be 0, 1, or both simultaneously. This allows them to solve complex problems much faster than traditional computers, with applications in medicine, materials science, and cryptography.
UPSC often asks about applications of emerging technologies like quantum computing and communication (GS Paper III). SSC exams may focus on basic definitions of quantum phenomena or key terms. Be prepared for questions on India's initiatives in quantum technology.
Remember 'Sun-Entangle' Sunlight makes Entanglement possible, saving Energy and making it Natural.
