This can be formulated either as a version of the adversary method that includes negative weights [9] (adding positive weights does not improve Ambainis’ original adversary method), as a c ...

Quantum Phase Transitions
... As we approach the phase transition, the correlations of the order parameter become long-ranged. Fluctuations of diverging size and duration (and vanishing energy) take the system between two distinct ground states across the critical point. When are quantum effects significant? Surprisingly, all n ...

Can many-valued logic help to comprehend quantum phenomena?
... Definition 2. Two propositions p, q such that p u q ≡ F will be called exclusive. Let us note that since we are in the realm of many-valued logic, exclusiveness of two propositions does not necessarily mean that at least one of them is certainly false. It is straightforward to check that p u q ≡ F m ...

In order to observe/measure the actual state, he has to ‘‘amplify’’ the action/energy differences DS up to the classical level, that is, up to the limit of being ...
