Introduction to loop quantum gravity
... General relativity has two main properties: diffeomorphism invariance and background independence. General relativity could be viewed as a field theory from the form of the Einstein-Hilbert action but this form does not influence the notions of space and time. Only diffeomorphism invariance and back ...

Quantum Stein`s lemma revisited, inequalities for quantum entropies
... can be established by an elementary argument on less than two pages: The new proof that we present below requires only the law of large numbers and a simple estimate on “overlaps” of certain projections with respect to some given quantum state. It is this simple proof of Stein’s lemma that we consid ...

In the learning game defined by protocol P , answer a to query q provides the information that the target function belongs to σqa . We also denote by Σq the set of ...

An Ontological Interpretation of the Wave Function - Philsci
... we can prepare a single measured system whose wave function is ψ(t) at a given instant t. For example, the measured system is an electron being in the ground state of a Hydrogen atom. Now, by a protective measurement, we can obtain the expectation value of the measured observable in this state with ...
