What if a blockchain network could run on quantum computers—and use a fraction of the energy?

On this episode of Quantum Matters, Postquant Labs co-founders Colton Dillion and Rick Karbach share how D-Wave's annealing quantum technology is integrated into the Quip Network, a quantum-classical blockchain network. They explain their “proof of useful work” model, where quantum and classical computers compete side by side to solve optimization problems as a way to validate transactions more efficiently. Early testing with D-Wave’s quantum processing unit suggests it can produce higher-quality solutions faster and with significantly lower energy use than comparable GPU-based approaches, while the classical compute decentralizes the network until quantum computers become more numerous.

Listen in to hear how this hybrid approach works in practice and why energy efficiency is quickly becoming one of the most important challenges in the future of blockchain systems.
