Abstract:
In the early 20th century, quantum theory transformed our understanding of matter and materials. The past decade has seen a second quantum revolution in condensed matter physics -- the highly entangled quantum matter. In fact, we now see that a myriad of unexpected, and previously disconnected phenomena, such as fractional charge, fractional or non-Abelian statistics, and emergent gauge bosons, have a common root in quantum many-body entanglement. Long-range entangled qubits can even give rise to gauge bosons and fermions at low energies, suggesting that these fundamental elements of nature may be the result of long-range entanglements.The long-range entanglement has provided a new conceptual lens, through which we now see that the world of materials is vastly richer than once imagined, and which may in time illuminate the quantum substructure of the universe itself.
