Engineering Innovations: The Internet, but Make it Quantum
Host Kristin Malavenda interviews Purdue ECE associate professor Joseph Luken about engineering “spooky action at a distance” into real technology, including quantum communication networks and the future quantum internet. Luken explains how the quantum internet would transmit qubits and distribute entanglement, why networking is essential for scaling quantum computing and sensing, and why Einstein objected to entanglement until Bell’s later experimental tests supported quantum predictions. He describes quantum key distribution (QKD), how it detects eavesdropping, and how it contrasts with post-quantum cryptography, arguing for pursuing both given the risk of future quantum attacks. Luken discusses recent industry momentum, predicts fault-tolerant quantum computing may arrive within 10 years, and emphasizes integrated photonics as critical to moving quantum systems off optics tables and reducing loss.
