Quantum Detectors & Sensors
ECE69500
Credit Hours:
3Learning Objective:
- Identify the fundamental differences between classical noise and quantum fluctuations in physical quantities (Quantum noise)
- Define the concept of coherence in space and time through the example of light (Quantum coherence)
- Describe the next generation of ultra-precision measurement tools (Quantum metrology)
- Design new systems for imaging, communications and a host of other applications exploiting superior detector technology (Quantum detectors)
- Recognize the fundamental limits of classical sensors and how to overcome them using quantum phenomena (Quantum sensing)
Description:
Learners will experience an overview of foundational ideas on which future quantum technology will be built. This course introduces the knowledge that will empower students to understand the difference between the quantum and classical realms. Specifically, this course teaches the concept of quantum detectors, which are central to a wide variety of quantum technologies from computing to networking. Students will also learn about quantum sensors and how they push the frontiers of existing classical sensor technology. Students can expect to learn skills for designing next generation information/communication/imaging systems that exploit unique functionality of quantum detectors and sensors.
