   What is entanglement in quantum physics?

   • Entanglement is at the heart of quantum physics and future quantum technologies. Like other aspects of quantum science, the phenomenon of entanglement reveals itself at very tiny, subatomic scales. When two particles, such as a pair of photons or electrons, become entangled, they remain connected even when separated by vast distances.

   Is entanglement a resource?

   • Thus entangled states are a resource that enables the realization of quantum interactions (or of quantum channels) in a setting where only LOCC are available, but they are consumed in the process. There are other applications where entanglement can be seen as a resource, e.g., private communication or distinguishing quantum states. [ 72 ]

   What are the applications of entanglement in quantum information theory?

   • Entanglement has many applications in quantum information theory. With the aid of entanglement, otherwise impossible tasks may be achieved. Among the best-known applications of entanglement are superdense coding and quantum teleportation. [ 86 ]

   Why is entanglement important?

   • The use of entanglement in communication, computation and quantum radar is an active area of research and development. In 1935, Albert Einstein, Boris Podolsky and Nathan Rosen published a paper on the counterintuitive predictions that quantum mechanics makes for pairs of objects prepared together in a particular way. [ 2 ]

   How can entanglement be observed?

   • Entanglement can be witnessed using macroscopic observables, such as the heat capacity (see ref. 6 for recent experiments). In fact, entanglement also serves as an order parameter characterizing quantum phase transitions 7, and there is growing evidence that quantum topological phase transitions can only be understood in terms of entanglement 8.

   Where does entanglement occur?

   • Entanglement can also occur among hundreds, millions, and even more particles. The phenomenon is thought to take place throughout nature, among the atoms and molecules in living species and within metals and other materials. When hundreds of particles become entangled, they still act as one unified object.

   Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance.
