Forget ransomware - most firms think quantum computing is the biggest security risk to come

• Quantum computers will soon be able to break modern-day encryption
• When that happens, nation-states can abuse the tech to steal sensitive files
• Organizations need to prepare today, Capgemini says

Sooner or later, quantum computers will be able to break through today’s encryption, and when that happens, critical industries such as defense, critical infrastructure, telecommunications, and others, will be at risk of nation-state attackers with enough resources to use the advanced tech for nefarious purposes such as espionage or data theft, research has warned.
