(DeccanChronicle) Quantum terrorists could bring down the future internet. The malicious actors could exploit the laws of quantum mechanics to destroy quantum information on a global scale.
Neil Johnson at George Washington University in Washington, DC, and his few colleagues have worked out how quantum terrorists could bring the quantum internet to its knees almost instantly and without revealing their identity.
If quantum terrorists work in unison, an entirely different scenario unfolds. Johnson and others reveal that if several attackers inject their quantum information into the network at the same instant, they can disrupt the global quantum state. The shocking conclusion is that it requires only three or more quantum terrorists working in unison. The findings reveal a new form of vulnerability that will enable hostile groups of [three or more] quantum-enabled adversaries to inflict maximal disruption on the global quantum state in such systems.
Just how this kind of attack could be countered isn’t entirely clear, although the team has one idea. “A countermeasure could be to embed future quantum technologies within redundant classical networks.”
