Google is warning that quantum computers will pose a significant threat to current encryption systems by 2029. The tech company says that these powerful computers can rapidly carry out complex tasks and break most existing encryption methods. This could expose sensitive data and compromise online security.
Currently, quantum computers are a nascent technology with great potential but also significant obstacles to widespread use. However, Google is urging other companies to follow its lead in building systems that harness the physics of quantum mechanics. The company recommends migrating to more advanced encryption systems now to protect sensitive data.
Experts agree that while a working quantum computer capable of breaking encryption may not be ready until the 2030s or 2050s, governments are already preparing for this eventuality. The UK’s National Cyber Security Centre has urged organisations to guard their systems against quantum hackers by 2035. To mitigate this threat, companies need to have classified documents that will remain unbreakable even with advanced quantum computers.
Google is not alone in its warning. Microsoft and universities across the US and UK are working on building quantum computer systems. These efforts are crucial in understanding the physics of quantum mechanics and developing new encryption methods to keep sensitive data secure.
