Physics vs. Code: Why Google’s ‘Quantum Money’ Could Make Blockchain Obsolete
Update: 2025-11-04
Description
Quantum Money: The Future of Digital Currency? - Researchers from Google and international collaborators propose a revolutionary concept for digital currency, replacing the need for blockchain with quantum money. This unique quantum object, based on the no-cloning theorem, is physically impossible to copy, making counterfeiting impossible. However, the system requires a central authority, unlike today's decentralized blockchains. The idea is still theoretical, but it marks a significant shift in the future of digital currency, rooted in quantum physics.
