Researchers at Postquant Labs have successfully utilized a D-Wave Advantage2 quantum computer to mine cryptocurrency on the Quip blockchain, demonstrating significant improvements in energy efficiency over conventional computing hardware.

Key Points

• The Quip blockchain network, active since April, uses quantum computing to solve proof-of-work optimization problems.
• D-Wave’s Advantage2 quantum computer wins 92 percent of the blocks it competes for on the Quip network.
• Using the quantum machine requires approximately 12.5 watts of power, compared to 1334 watts for conventional computers.
• The project aims to democratize access to quantum hardware by creating a decentralized, worldwide distributed quantum computing network.
• Other firms, including BTQ Technologies and Quandela, are also exploring quantum-based proof-of-work applications.

Why it Matters

This experiment suggests that quantum technology could significantly reduce the massive energy consumption associated with traditional cryptocurrency mining. However, the high capital expenditure required to build and maintain quantum hardware remains a major hurdle for scaling this approach to a global level.
