Galilei covariance and Einstein`s equivalence principle in quantum
... holds for every vector state |ψ, shows that the original description will always be retrieved under cyclic transformations. This ought to be so, as the transformation ĜXk reflects only a change in the theoretical description; it is not real. That is, absolutely no physical intervention is implied ...

Resilient Quantum Computation in Correlated Environments: A Quantum Phase Transition Perspective
... (QEC) is the ‘‘threshold theorem’’ [1]. Even though QEC is a perturbative method [1,2], the threshold theorem states that, provided the noise strength is below a critical value, quantum information can be protected for arbitrarily long times. This remarkable theorem was first derived for stochastic ...

classical / quantum theory of 2-dimensional hydrogen
