Conventions in relativity theory and quantum mechanics
... This is a preference which cannot be motivated by geometry or epistemology; it is purely physical. However, any such Lorentz transformation will result in a non-invariance of the theory of sound or any other phenomena which are not directly dominated by electromagnetism. There, an asymmetry will ap ...

Equality and Identity and (In)distinguishability in Classical and Quantum Mechanics from the Point of View of Newton's Notion of State
... Pauli’s exclusion principle: 2 electrons di¤er in at least one quantum number –however: it does not say, which electron is in which state (entanglement); The quanta occupying an oscillator loose their individuality: Say, 12 quanta in state E12 occupy all together the one 12-quanta state, not 12 sing ...

The Learnability of Quantum States
... Theorem (implicit in Lloyd 1996): BOSONSAMPLING QSAMPLING Proof Sketch: We need to simulate a system of n bosons on a conventional quantum computer The basis states |s1,…,sm (s1+…+sm=n) just record the occupation number of each mode Given any “scattering matrix” UCmm on the m modes, we can dec ...

Creation of entangled states in coupled quantum dots via adiabatic... C. Creatore, R. T. Brierley, R. T. Phillips,
... An important feature of our proposal is that it does not require precise engineering of individual quantum dots. In particular, we do not require that the dots in a particular pair have almost degenerate exciton levels. Instead, we consider an ensemble of pairs, a subset of which will obey this crit ...
