- Quantum computing could be the next revolution in computing technology. Applications include optimization, quantum chemistry, material science, cryptography and machine learning.
- Quantum sensing could have far reaching impact on positioning, navigation and timing, enabling GPS-free positioning and long distance inertial navigation.
- Congress recently passed the National Quantum Initiative Act, funding $1.2B to NSF and DOE for research
- Lots of research activity in government, industry and academia.
- LLNL has funded many LDRDs exploring quantum technologies over the past several years.

Quantum information and sensing technologies are entering a period of rapid growth and discovery. This series of hour-long lectures is designed to provide an introduction to a range of topics in quantum information and sensing. The lecture series consist of two parts spread over nine lectures (see detailed outline below):

- Quantum devices, control and interfacing to these devices, and how errors are modeled in quantum systems
- Applications of quantum information processing and sensing including: quantum computing and algorithms, sensing with quantum devices, and quantum communications

Learn about the fundamentals of these technologies, research directions, and how to separate reality from all the hype.

Detailed knowledge of quantum mechanics is not required for these lectures. Necessary background will be provided as needed.

Lecture dates, times and locations will be announced in Newsline.

This lecture series is sponsored by the Center for Advanced Signal and Image Sciences and the Engineering Directorate.
