A recent study conducted by Shanghai University indicates that D-Wave's quantum annealing technology could compromise encryption systems such as RSA and AES. Quantum computing could pose a threat to cybersecurity; organizations should now focus on implementing quantum-safe encryption measures.
What happened
In a recent study, a team of Chinese researchers, led by Wang Chao from Shanghai University, has demonstrated the potential for quantum computing to compromise the encryption systems that safeguard sensitive global data. Their research, published in the Chinese Journal of Computers, reveals that D-Wave’s quantum annealing technology can undermine widely used cryptographic methods, such as RSA and Advanced Encryption Standard (AES).
The researchers successfully used the D-Wave Advantage system to factor a 50-bit RSA integer, a task previously thought to be unachievable for current quantum machines. This achievement demonstrates the accelerating pace at which quantum computing is approaching capabilities that could threaten modern cybersecurity systems.
Going deeper
The study, titled Quantum Annealing Public Key Cryptographic Attack Algorithm Based on D-Wave Advantage, focused on leveraging quantum annealing to solve cryptographic challenges. Quantum annealing transforms cryptographic attacks into combinatorial optimization problems, which quantum systems are adept at solving.
The experiments targeted RSA encryption and algorithms foundational to AES encryption, such as Present, Rectangle, and Gift-64 block ciphers. These algorithms, integral to securing everything from financial transactions to government communications, were shown to be vulnerable to quantum-powered attacks.
The research further highlighted the threat to the Substitution-Permutation Network (SPN) structure, a cryptographic backbone in many encryption systems.

Why it matters
Encryption is the cornerstone of digital security. From securing bank transactions to protecting confidential government data, modern life depends on encryption standards like RSA and AES. The ability of quantum systems to potentially bypass these safeguards could upend global cybersecurity.
What to look for
This breakthrough signals the need to transition toward quantum-resistant cryptographic systems, such as those being explored under the umbrella of Post-Quantum Cryptography (PQC). Governments, tech giants, and researchers worldwide must act to ensure that critical data remains secure in the face of quantum advancements.
The study also serves as a wake-up call for industries relying on SPN-based encryption, which is especially susceptible to quantum disruption. With quantum computing rapidly evolving, proactive measures are essential to stay ahead of potential threats.
