Currently Teaching
PHYS-251
Principles and Applications of Quantum Technology
3 Credits
This course will provide an introduction to principles of quantum mechanics, hardware platforms, and applications of quantum technology. Two state systems, such as photon polarization, will be used to introduce mathematical formalism including Dirac notation for quantum states, operators, observables, measurements, composite systems and entanglement. The course will overview different platforms for physically realizing quantum bits (qubits) and operations on quantum bits. Real-world effects on quantum systems, including coherence and decoherence and reducing classical noise in quantum hardware will be discussed. Quantum limits on precision of sensors and imaging as well quantum simulations will be primary applications.
PHYS-495
Advanced Physics Research
1 - 3 Credits
This course is a faculty-directed student project or research involving laboratory work, computer modeling, or theoretical calculations that could be considered of an original nature. The level of study is appropriate for students in their final two years of study.
PHYS-667
Quantum Optics
3 Credits
This course explores the fundamental nature of electromagnetic radiation. This course will introduce the student to the second quantized description of light with special attention to its role in a modern understanding of and far reaching utility in emerging technologies. Starting with an appropriate formulation for the quantum mechanical electromagnetic radiation field, we will study quantum mechanical models for interactions with matter, and we will test these models through a series of experiments.
PHYS-790
