... by neither heat nor work in the classical SZE, it is not the case with the quantum SZE. This process can be modeled as that of increasing the height of the potential barrier. In quantum mechanics, energy levels then vary, contributing to the QTW. This process can be performed isothermally so that th ...

... of a still-mysterious complex “wave-function” for massive particles. But the EinsteinPlanck formula Eq.(2) was first written down for photons, and surely applies to them as well. A classical electromagnetic wave whose electric field could be given by Eq.(1) is quantum-mechanically a collection of many ...

Logic of Quantum Mechanics
... In fact, 53 need not be stated as a postulate at all, but can be regarded as a definition of logical equivalence. Pursuing this line of thought, one can interpret as a "physical quality," the set of all experimental propositions logically equivalent to a given experimental proposition.14 Now if one ...

Defining and Measuring Multi-partite Entanglement
... This figure shows Pmax as a function of the number of iterations, for different number of quantum bits needed in the quantum register (6 to 12). It can be seen that during the operation of the algorithm entanglement is created, and then removed. It returns to zero exactly at the time when the measur ...
