چکیده
We demonstrate a general method to measure the quantum state of an angular momentum of arbitrary magnitude. The 2F 1 1 3 2F 1 1 density matrix is completely determined from a set of SternGerlach measurements with 4F 1 1 different orientations of the quantization axis. We implement the protocol for laser cooled Cesium atoms in the 6S1 2 F 4 hyperfine ground state and apply it to a variety of test states prepared by optical pumping and Larmor precession. A comparison of input and measured states shows typical reconstruction fidelities F * 0.95.

A systematic review on reminder systems in physical therapy
Background: The main goal of physical therapy is to help the patient gain a better health status. Several studies have investigated the use of reminders to prevent such failures on the patients’ side. This article presents a systematic review of the literature concerning reminders in physical therapy. Methods: Databases were searched until May 2017 and literatures were found from April 1...
