Follow The Post-Quantum World, where Protiviti and our guests explore quantum computing and its business impacts, benefits and threats. Quantum computing capabilities are exploding, causing disruption and opportunities, but many technology and business leaders still dont understand the impact quantum will have on their business. Protiviti is helping organizations get post-quantum ready. In our bi-weekly podcast series, The Post-Quantum World, Protiviti Associate Director and host Konstantinos Karagiannis is joined by quantum computing experts to discuss hot topics in quantum computing, including the business impact, benefits and threats of this exciting new capability.

Quantum Money and Self-Destructing Signatures — with NTT
Episode 122
Wednesday, 18 February, 2026
A one-shot signature is a new quantum computing tool that lets people verify information publicly using a quantum signing key that destroys itself after use. This “proof of destruction” makes sure the key can only be used once, which could lead to cryptographic solutions that classical math could not achieve. Host Konstantinos Karagiannis talks with Omri Shmueli, a cryptographer and postdoctoral research fellow at NTT Research, about how one-shot signatures might change digital finance and secure communication. Shmueli shares how this technology could make decentralized cryptocurrency possible without a blockchain or help solve the big scalability problems of current blockchains by letting users create their own unique quantum money. The episode also looks at how unclonable quantum keys could give users proof that not only do they have a secret key, but they are the only person in the world who does.
