Microsoft’s Majorana Chip, Topological Qubits & Quantum Machine Learning

In this episode, I sit down with Dr. Nathan Wiebe from the Department of Computer Science at the University of Toronto. Prof. Wiebe specializes in quantum simulation, machine learning, and quantum computing. We talk about the fundamentals of quantum computing, explore Microsoft’s new “Majorana” quantum chip, and discuss what the future holds for quantum machine learning, error correction, and more. Whether you’re a seasoned researcher or just curious about the world of qubits, this conversation offers insights into the rapidly evolving quantum landscape.
