Protect Data from Quantum Computers Guide How to Protect Your Data from Quantum Computers 14 min read The Quantum Threat Is Not Hypothetical Quantum computers will break most of today's encryption. This is not speculation or fear-mongering. It is a mathematical certainty based on Shor's algorithm, published in 1994 and verified by every cryptographer who has examined it since. The only question is when quantum hardware becomes powerful enough to run the algorithm at scale. The timeline matters because of a strategy called "harvest now, decrypt later." Intelligence agencies and sophisticated attackers are already recording encrypted internet traffic and storing it in massive data centers. They cannot read it today. But when quantum computers mature, they will decrypt everything they have collected. Your medical records from 2024, your financial transactions, your private messages, and your legal documents could all become readable.…
