We have recently submitted a scientific article to arXiv titled “Cyclic Measurements and Simplified Quantum State Tomography” (link: https://arxiv.org/abs/2404.18847). The authors of the paper include Víctor González Avella, Jakub Czartowski, Dardo Goyeneche, and Karol Życzkowski. This publication is a direct outcome of the goals set during Jakub’s recent visit, which was highlighted in our news article dated 25th March 2024.
In this study, we have developed optimal sets of measurements that uniquely determine the state of a quantum system. This method is designed to minimise the propagation of statistical errors and greatly simplify the experimental setup required for implementing the procedure. From the perspective of quantum computing, accurate determination of the quantum state is essential, as it equates to reading information from the quantum computer. This process is crucial for practical applications such as verifying and validating the accuracy of quantum operations and contrasting theory with experimentation.
