The quantum threat is becoming increasingly urgent, with IBM planning to deliver 1,000 logical qubits by 2033, which could enable quantum computers to break RSA-2048 encryption by 2035.
According to Jon Lau, director of cybersecurity at the Agency for Science, Technology and Research in Singapore, the timeline could accelerate further if state actors or well-funded entities gain early access to quantum systems.
"If you tell them it's 2035, they say 'that's 10 years later - why worry about it now?' … That's why I brought in about harvest now, decrypt later, because that's the key reason why we have to go in now,"
Lau emphasizes that organizations must address encryption and key management to mitigate the quantum threat, rather than dismissing it as a distant concern.
Threat actors are already stockpiling encrypted data, highlighting the need for urgent action to protect against "harvest now, decrypt later" attacks.
Quantum threat demands immediate attention.
