So why hasn't anything materialized? On TWiST in Tokyo, Jason sits down with Yaqumo CEO Kazuhiro Nakashoji and discusses what needed to change (like better algorithms and hardware), and why we may finally be nearing quantum's big moment. Find out why quantum machines are so error-prone, explore the unusual international quantum supply chain, and get a heads-up about the cryptography reckoning coming for your Bitcoin.
