Public (asymmetric) key cryptography secures the financial system via digital signatures and certificates. Being able to forge those with a sufficiently capable quantum system would be problematic to say the least. Symmetric cryptographic algorithms, like AES-256, are considered to be more resistant to quantum computers, so the application of Grover's algorithm [PDF] in a quantum system isn't expected to alter the cryptographic landscape., Scientists in China claim they have found a way for current-generation quantum computers to crack the RSA algorithm underlying the most common form of online encryption. The researchers said the encryption could be broken with a 372-quantum-bit (qubit) system using hybrid quantum-classical methods to overcome scaling limitations.The Chinese paper “Factoring integers with sublinear resources , Chinese researchers have surprised the security community by claiming to have cracked low-level RSA encryption – the standard encryption method used for secure data transmissions around the world – using a hybrid of a quantum and classical computer. The scientists say their method could be used to defeat advanced 2048-bit RSA encryption using a 372-qubit quantum computer, something which .
The research team, led by Wang Chao from Shanghai University, found that D-Wave’s quantum computers can optimize problem-solving in a way that makes it possible to attack encryption methods such , In late 2022, a remarkable claim jolted the cryptography and quantum computing communities.A team of 24 Chinese researchers quietly posted a preprint on arXiv claiming they had factored a 48-bit RSA-style integer using a 10-qubit quantum computer. This was no mere 15 or 21 (the trivial benchmarks often cited in early quantum experiments) – it was a 48-bit semiprime (a product of two primes , The paper, titled "Factoring integers with sublinear resources on a superconducting quantum processor," suggests that the application of Claus Peter Schnorr's recent factoring algorithm, in conjunction with a quantum approximate optimization algorithm , can break asymmetric RSA-2048 encryption using a non-fault tolerant (NISQ, or noisy intermediate scale quantum) quantum computer with only 372 , But in a study published in the journal Chinese Journal of Computers in May, researchers found that D-Wave Advantage — a 5,760-qubit machine created by California-based D-Wave Quantum Systems , The research used quantum annealing, a method focused on solving optimization problems, rather than a general-purpose quantum computer, which can execute broader tasks like Shor’s algorithm. D-Wave’s quantum annealer is not yet capable of handling the large numbers necessary for breaking RSA encryption of today effectively., In 2022, Chinese researchers described a potential method to break RSA-2048 encryption, but argued that their method would require "millions of qubits" and therefore was "far beyond current .
