What is quantum physics and what makes it so weird? We'll introduce key aspects of quantum physics with an aim to explain why it differs from everyday 'classical' physics. Quantum-enabled devices like the laser and atomic clocks for GPS will be explained. We will also discuss the breakthroughs driving the 2nd quantum technology revolution surrounding quantum simulators, sensors, and computers. Seminar discussions and a laser lab will help illustrate core principles, including the atomic clock mechanism. Visits to campus laboratories will introduce cutting-edge quantum experiments. This IntroSem is designed for those likely to go on to major in the humanities or in a STEM program outside of the natural sciences. (Likely STEM majors are instead encouraged to take PHYSICS 100-level quantum courses upon completion of pre-requirements.) While basic familiarity with high school physics is recommended, qualitative explanations will be emphasized. By the end of the quarter, you will be able to explain the key tenets of quantum physics, how it has enabled current technology, and what new technologies might emerge from the 2nd quantum revolution.
