This course covers the physics of trapped ions at the quantum level described as harmonic oscillators coupled to spin systems, for which the 2012 Nobel prize was awarded. Trapped-ion systems have achieved an extraordinary level of control and provide leading technologies for quantum information processing and quantum metrology.

We will cover experimental issues in making measurements in modern physics experiments. The primary challenge in any measurement is achieving good signal to noise. We will cover areas such as optical propagation, electronics, noise limits and feedback control. Methods for stabilizing frequencies and intensities of laser systems will also be described.

Recent years have witnessed incredible progress in the development of new quantum technologies driven by their application in quantum information, metrology, high precision spectroscopy and quantum sensing. This course will present how these emerging technologies are powerful tools to address open questions of the Standard Model in a complementary way to what is done at the high energy frontier.
