Quantum entanglement is a phenomenon in quantum mechanics where two or more particles become correlated in a way that their properties become dependent on each other, even when they are separated by large distances. This phenomenon has been the subject of intense study in both physics and computer science due to its potential for various applications, including quantum computing and quantum communication.
The concept of quantum entanglement was first introduced by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935 in a paper known as the EPR paradox. However, it wasn’t until the 1960s that experimental evidence for entanglement was obtained by John Bell in a series of now-famous Bell’s inequality experiments.
Today, entanglement is widely studied in many different areas of physics, including quantum information theory, condensed matter physics, and quantum field theory. It has also been shown to have important practical applications, such as in the development of quantum cryptography and quantum teleportation.
