A quantum central limit theorem for sums of IID
... In this note we shall prove a general central limit theorem for sums of quantum (tensor) independent identically random variables which can be seen as an analytic extension of the algebraic CLT of Giri and von Waldenfels [GW]. Our main tool is a quantum version of the Lévy-Cramér continuity theorem ...

Three-dimensional solids in the limit of high magnetic fields
... recently. Superconductivity is destroyed by a high magnetic field, for the supercurrents that circulate in response to the field and provide the Meissner effect increase the energy of the system. Above a certain field, the nonsuperconducting state has a lower energy. This is called “diamagnetic pair ...

On Quantum Generalizations of Information
... has many advantages. While probability distributions are generally over atomic symbols, a density operator can be considered a probability distribution over eigen kets. Depending on the kets’ internal structure, they can encode a lot of information about some system. If the system is a complex of mo ...

Is the second law of thermodynamics always applicable
... attempts of Prigogine [2], who advocates the use of quantum wave functions outside of a Hilbert space in order to fix the arrow of time, seem difficult to reconcile with our results. Admittedly, the ‘pure’ eigenstates of a whole system (all external thermal or energy sources being included) always p ...
