摘要:

我们提出了实验量子层析术的7-和8-维量子系统的基础上投影测量的相互无偏的基础上(MUB-QT)。MUB-QT的优点之一是它需要从最少数量的碱基进行投影。在我们的方案中,使用单光子的传播模式对高维量子系统进行编码,并且我们利用可编程空间光调制器的幅度和相位调制能力来实现MUB-QT。

英文摘要:

We present the experimental quantum tomography of 7- and 8-dimensional quantum systems based on projective measurements in the mutually unbiased basis (MUB-QT). One of the advantages of MUB-QT is that it requires projections from a minimal number of bases to be performed. In our scheme, the higher dimensional quantum systems are encoded using the propagation modes of single photons, and we take advantage of the capabilities of amplitude- and phase-modulation of programmable spatial light modulators to implement the MUB-QT.
