旋转偏振滤光片是否相当于改变光子偏振测量基础?
Rotating polarizing filters is indeed equivalent to changing the photon polarization measurement basis in the realm of quantum information based on quantum optics, particularly concerning photon polarization. Understanding this concept is fundamental in comprehending the principles underlying quantum information processing and quantum communication protocols. In quantum mechanics, the polarization of a photon refers to the

如何通过俘获在量子点中的电子或激子来实现量子位?
A qubit, the fundamental unit of quantum information, can indeed be implemented by an electron or an exciton trapped in a quantum dot. Quantum dots are nanoscale semiconductor structures that confine electrons in three dimensions. These nanostructues (sometimes referred to as artificial atoms, but not truly accurately due to a size of localization and hence
