An Accidental Relationship Between a Relative Quantum
... Concurrence and other measures of entanglement, being nonlinear functions of the density operator, can not be directly measured. Therefore, the search of observables related to entanglement, including entanglement witnesses, is an important goal. In this paper we show a result in that direction. For ...

Enhancement of quantum dot peak-spacing fluctuations
... Several experimental studies [1-3] have recently demonstrated that the fluctuations in the ground-state energy of a quantum dot, which are manifested in the fluctuations in the resonanttunneling-peak spacings, are much larger than what one would expect from models that ignore electron correlations. ...

Say we want to make an ’optical Stern-Gerlach’ experiment, this will work well since the photon, even though it is a spin-one particle, only assume the spin states -1 and 11 . The spin ...

However, it remains that the pure state (1)/(2) is a more subtle entity than Einstein’s mixed state (4). We claim that pure states such as eqs. (1)/(2) can exist in Nature, and t ...
