Is spacetime a quantum error-correcting code?
... Nicely capture some central features of full blown gauge/gravity duality, and provide an explicit dictionary relating bulk and boundary observables. Illustrate how quantum error correction resolves the causal wedge puzzle, and how the operators deep in the entanglement wedge can be reconstructed. Re ...

The formal context of Noether’s theorems is Lagrangian field theory wherein equations of motion are obtained through a variational procedure (Hamilton’s principle) from the action integral, S = L d x. Noether’s theorems are discussed in detail in Earman (2002) and Brading and Brown (this volume). N ...

Moreover, if M reduces to M and N reduces to N , the reduced redex in M is (up to quantum bits) the same redex reduced in N. This means that λq has cl ...
