According to forecasts by technology giants, quantum computers capable of breaking all existing digital encryption systems within minutes could fall into the hands of cyberattackers by 2029.
elchi reports that the moment when encryption methods that form the basis of internet security will be rendered completely ineffective by quantum technology is called “Q-Day” by experts.
If quantum computers reach this power, all kinds of sensitive data protected by today’s algorithms, such as internet banking, personal emails, and cryptocurrency wallets, will become vulnerable.
The fact that industry representatives point to 2029 as the target date indicates that governments and companies have less time than expected to take action.
Quantum computers can break complex mathematical codes that traditional computers cannot solve in seconds, thanks to the “qubit” system that can calculate multiple probabilities simultaneously.
It is reported that malicious actors are already obtaining and storing critical data in encrypted form, waiting for the day when quantum technology is fully ready. According to this strategy, known as “harvest now, decrypt later,” even if security software is updated in the future, historical health data and state secrets remain at risk.
