On episode #143 of Eye on AI, Craig Smith sits down with Scott Aaronson, Schlumberger Centennial Chair of Computer Science at The University of Texas and director of its Quantum Information Center.
In this episode, we cut through the quantum computing hype and explore its profound implications for AI. We reveal the practicality of quantum computing, examining how companies are leveraging it to solve intricate problems, like vehicle routing, using D-Wave systems. Scott and I delve into the distinctions between quantum annealing and Grover-type speedups, shedding light on the potential of hybrid solutions that blend classical and quantum elements.
Shifting gears, we delve into the synergy between quantum computing and AI safety. Scott shares insights from his work at OpenAI, particularly a project aimed at fine-tuning language models like GPT for detecting AI-generated text, highlighting the implications of such advanced AI technology's potential misuse.
