论文摘要
我们为宏观QUDIT系统分析开发了一个一般方案：a）引入一组集体观测值，以最佳方式表征了Qudits的宏观特性； b）构造投影$ \ tilde {q} $ - $ n $ qudit系统的功能，包含完整的宏观信息； c）针对一般和对称$ n $ qudit状态提出集体层析成像协议。详细分析了$ n $ qutrit的示例，并与$ n $ qubit的案例进行了比较
We develop a general scheme for an analysis of macroscopic qudit systems: a) introduce a set of collective observables, which characterizes the macroscopic properties of qudits in an optimal way; b) construct projected $\tilde{Q}$-functions for $N$ qudit systems, containing full macroscopic information; c) propose a collective tomographic protocol both for a general and symmetric $N$-qudit states. The example of $N$-qutrit is analyzed in details and compared to $N$-qubit case
