Browsing: Quantum Entanglement

Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles interact in ways such 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 counterintuitive aspect of quantum mechanics suggests that the state of one entangled particle can instantaneously affect the state of another, no matter how far apart they are, a phenomenon that Einstein famously referred to as “spooky action at a distance.” Entanglement is a fundamental element of quantum computing and quantum cryptography, as it allows for the creation of highly secure communication channels and the performance of computational tasks at speeds unachievable by classical systems. The properties of entangled particles are used to test the principles of quantum mechanics and have potential applications in developing new technologies such as quantum networks and sensors.
