Superconducting Qubits, STAR Architecture, and Diamond-Spin Qubits with Dr. Shintaro Sato

Fujitsu's quantum roadmap is one of the most ambitious in the world — 10,000+ physical qubits and 250 logical qubits by 2030 — and Dr. Shintaro Sato is the person responsible for making it real. In this episode, Sebastian talks with Sato about the engineering realities of scaling superconducting quantum computers, a novel approach to fault-tolerant logical operations called STAR architecture, and a just-announced tin-vacancy diamond-spin prototype that Fujitsu intends to use as a photonic interconnect between quantum modules. If you're tracking the path from NISQ to fault-tolerant quantum computing, this conversation covers the full stack.
