Immunity of information encoded in singlet states against one particle loss

We present a pictorial representation of quantum many-body wavefunctions, in which a wavefunction characterizing a chain of n qudits is mapped to an image (and which we call Qubism). The main property of the plotting scheme is the recursivity: increasing the number of qubits reflects in an increase in the image resolution. Thus, the plots are typically fractal-like, at least for translationally invariant states. Many features of the wavefunction, such as magnetization, entanglement and criticality, are represented by visual properties of the images.<br><br>Presented on: http://qcmc2012.org/, http://www.eccs2012.eu/, http://www.uibk.ac.at/th-physik/qism2012/

我们提出了一种量子多体波函数（quantum many-body wavefunctions）的可视化表示方案：将描述n个量子数位（qudits）链的波函数映射为图像，我们将该方法命名为Qubism。该绘图方案的核心特性为递归性：量子数位数量的增加会对应图像分辨率的提升。因此，生成的图像通常呈现类分形特征，至少对于平移不变态而言是如此。波函数的诸多物理特性，例如磁化强度、量子纠缠与临界行为，均可通过图像的视觉特征体现出来。
