The laws of quantum mechanics state that it is impossible to copy quantum information, leading many to believe that quantum computers are impervious to hacking. However, recent research has revealed a new threat to quantum computers in the form of row-hammer attacks. These attacks disrupt calculations on quantum computers and pose a significant risk to their security.
Row-hammer attacks are not new and have traditionally targeted dynamic random-access memory (DRAM) in conventional computers. These attacks exploit unintended electrical interactions within DRAM modules to manipulate data and compromise the system’s security. Now, two independent teams of researchers have found ways to adapt row-hammer attacks for use against quantum computers.
By exploiting similar vulnerabilities in quantum hardware, these researchers have demonstrated that quantum computers are not immune to attacks. This development raises concerns about the security of quantum computing systems and the potential for malicious actors to exploit these vulnerabilities for their gain.
