How Quantum Entanglement Creates Entropy
What is Entanglement ? :
Quantum entanglement is one of the uber-bizarre phenomena seen when things get itty-bitty, or inside the quantum realm. When two or more particles link up in a certain way, no matter how far apart they are in space, their states remain linked. That means they share a common, unified quantum state. So observations of one of the particles can automatically provide information about the other entangled particles, regardless of the distance between them. And any action to one of these particles will invariably impact the others in the entangled system. ( Learn more )
What is Entropy ? :
Entropy is probably the most misunderstood of thermodynamic properties. While temperature and pressure are easily measured and the volume of a system is obvious, entropy cannot be observed directly and there are no entropy meters. What’s the solution? ( Learn more )
Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder – or as the amount of useful work that you can get from it – or as the information hidden by the system. Despite the seeming ambiguity in its definition, many physicists hold entropy to be behind one of the most fundamental laws of physics.
