it's worth noting that Signal has a history of prioritizing privacy and security in its messaging app. The mention of protecting chats from quantum computers suggests a consideration of post-quantum cryptography. Quantum computers have the potential to break certain cryptographic algorithms that are currently considered secure. To address this, researchers are working on developing post-quantum cryptographic algorithms that would be resistant to attacks by quantum computers. If Signal or any other messaging app were to adopt a new cryptographic algorithm or technique, it would likely be to ensure the continued security of user communications in the face of advancing technologies, including the potential future development of quantum computers capable of breaking existing encryption methods. For the latest and most accurate information, I recommend checking Signal's official communications, blog posts, or announcements for any updates on their security measures, especially regarding protection against quantum computing threats.
