Cyber Security in the Quantum Era

CYBER SECURITY DEALS with the protection of computer systems from attacks that could compromise the hardware, software or information. These attacks, by allowing unauthorized use, could leak private information and cause damage or disruption. In the future, the part of everyday life and economy requiring computer systems is bound to increase further and become fully dominant. Cyber warfare and cyber crime will be common and the role of cyber security crucial. SINCE THE COMPUTER systems (and attackers) evolve both in hardware and software, the constant evolution of this field is of high importance. Arguably the most dramatic development that one can envision is a change in the paradigm of computational model used. Quantum technologies appear to bring us close to such a change. Here, we explore the research field that lies on the intersection of cyber security and quantum technologies research.
