What is quantum entanglement?
Answers

Quantum entanglement is a fundamental phenomenon in quantum mechanics where two or more particles become interconnected in such a way that the quantum state of each particle cannot be described independently of the state of the others, even when the particles are separated by large distances. This means that the measurement of one particle's properties, like its spin or polarization, instantly affects the state of the other particle(s), regardless of the distance separating them.
Entanglement is a key feature of quantum mechanics that contrasts sharply with classical physics, where objects are considered to have definite properties independent of measurement. The phenomenon has been famously described by Albert Einstein as "spooky action at a distance," as it implies a strong correlation that seems to defy classical intuitions about locality and causation.
Entangled particles are often used in various applications, including quantum computing, quantum cryptography, and quantum teleportation, where the unique properties of entanglement can lead to advanced processing capabilities and secure communication methods.
