You may be vaguely aware of the term ‘quantum computing’ from media reports. But what you may not have picked up on is that one of the primary uses for quantum computers may be to break data encryption. Furthermore, you may not realize that if three-letter agencies can save off our encrypted emails and messages now, this could mean they could read them in the future when sufficiently powerful quantum computing becomes viable. How does this work? And what can we do about it now to protect our privacy in the future? We’ll dig into all of this today with Brandon Sundh from Tuta (formerly Tutanota), a prominent secure email company, who is already deploying such protections.
