Patent status of entanglement swapping could be challenged
Entanglement swapping, a quantum process linking particles over long distances, plays a key role in enabling quantum repeaters for secure quantum networks. But its patent eligibility is uncertain. Legal experts note it may be considered just a natural law—rather than a patentable invention—especially if a patent claims only the well-known quantum mechanics processes without a specific technical improvement.
- Entanglement swapping connects distant quantum nodes
- Enables 'quantum repeaters' for secure long-range quantum links
- Patent eligibility may be rejected for being a natural law
- Patents must show technical improvements, not just abstract ideas
