A Classic Hacking Technique Works on Some Quantum Computers

Quantum mechanics is known for its unique properties, but it's clear that not all quantum computers are immune to hacking attempts. Two independent teams of researchers have recently discovered methods to disrupt calculations on quantum computers using a technique called row-hammer attack.

The laws of quantum mechanics prohibit the copying of quantum information, making it seem like quantum computers should be completely secure. However, this assumption is not entirely accurate. Researchers have found ways to exploit these limitations and develop methods to manipulate quantum computer operations.

Row-hammer attacks are a type of hardware exploitation technique that targets dynamic random-access memory (DRAM), a crucial component for short-term information storage in traditional computers. By generating specific electrical signals, an attacker can induce unwanted interactions between parts of the DRAM, ultimately causing errors and disruptions to the system.

In this context, researchers have adapted row-hammer attacks to work on quantum computers. They achieve this by manipulating the electromagnetic fields that govern quantum computing operations. This new approach allows attackers to disturb the delicate balance of quantum bits (qubits) and introduce noise into the calculations, effectively crashing the quantum computer's performance.

These findings demonstrate that, while quantum mechanics may provide certain security benefits, it is not a silver bullet against all hacking attempts. The adaptation of row-hammer attacks to quantum computing represents an important milestone in the ongoing exploration of quantum vulnerability and resilience.

The implications of this discovery are significant, as they underscore the importance of understanding the fundamental laws governing both traditional computers and quantum systems. By pushing the boundaries of known security techniques and exploring new vulnerabilities, researchers can better equip us with tools to protect ourselves against increasingly sophisticated threats.
