Episode Details

A behind-the-scenes look at how PsiQuantum is turning quantum computing into a silicon-scale manufacturing problem. In this condensed summary of the original Sourcery episode, host Molly O'Shea speaks with Er-Xuan Ping about the silicon photonic chipset, 300 mm wafers, molecular beam epitaxy (MBE), and the extreme materials-science discipline needed to grow BTO, strontium titanate, and barium titanate films with nanometer-level precision. Learn why clean rooms, ultra-high vacuum, automated wafer handling, and exact composition ratios matter for single-photon quantum computers—and how optical interference becomes a built-in quality-control tool. This shorter version keeps the key insights on semiconductor fabrication, thin-film growth, and quantum hardware manufacturing while saving you time. Listen now to get the key ideas in minutes.
