In this episode of Decoding the Future by Fujitsu, host Mahesh Krishnan sits down with quantum physicist Dr. Rose Auffeldt (ANU) to break down one of the most misunderstood technologies of our time.

From superposition and entanglement to cryptography, drug discovery, and real-world applications, this conversation strips quantum computing back to its fundamentals, without losing the depth.

If you’ve ever felt like quantum computing “almost makes sense”… this is the episode that finally clicks.
