*Illustrative imageIoT Security Protected by AI
The lab studies mechanisms that use AI to verify whether networks and IoT devices are operating correctly, and techniques for detecting hardware Trojans, which are malicious circuits secretly inserted into a circuit.
*Illustrative imageAI, Quantum Technology, and Geographic Information
Targeting familiar devices such as smartwatches and smartphones, the lab studies pedestrian navigation using AI and quantum technology, and map-based travel plan recommendation.
*Illustrative imageApplications of Quantum Computers
The lab studies practical uses and applications of quantum computers, which compute in a different way from conventional computers. It also uses simulators installed in the lab.
