An analytic formula determining quantum pointer basis and its application to a flying bullet

备注：
This paper was withdrawn by the author because the notion of the robustness on the object state is not suitable to establish a more general theory addressing the quantum measurement problem. Please refer the renewed paper, arXiv:1606.02418, which provides answers to the questions of where and when collapse occurs, how the collapse basis is determined, what determines the observables, etc

摘要：

我们提出了一个确定宏观物体与环境相互作用的量子指针基的一般方案。与退相干程序不同，我们的指针基不需要对纠缠的鲁棒性，但需要对对象状态本身的鲁棒性。所提出的指针基不依赖于主方程，因此很容易计算，因为它有一个时间局部解析公式。我们表明，作为一个令人信服的例子，所提出的公式给出了一个令人满意的指针基础的宏观飞行体，如子弹的指针状态应该有明确的动量以及高度本地化的位置。

英文摘要：

We propose a general scheme determining the quantum pointer basis of a macroscopic object interacting with environment. Unlike the decoherence program, our pointer basis does not require robustness against entanglement, but require robustness on the object state itself. The proposed pointer basis does not rely on master equations, and so is easily calculable since it has a time-local analytic formula. We show that, as a convincing example, the proposed formula gives an satisfactory pointer basis of a macroscopic flying body such as a bullet whose pointer states should have well-defined momentum as well as highly-localized position.
