Fujitsu quantum simulator assesses vulnerability of RSA cryptosystem to potential quantum computer cryptography threat
TOKYO, Jan 23, 2023 - (JCN Newswire via SEAPRWire.com) - As concerns mount surrounding the potential threat posed by quantum computing to existing cryptographic methods, Fujitsu today revealed that it conducted successful trials to evaluate the widely-used RSA cryptosystem (1) for possible vulnerability to code-cracking by quantum computers.Fujitsu conducted the trials in January 2023 using its 39-qubit quantum simulator to assess how difficult it would be for quantum computers to crack existing RSA cryptography, using a Shor's algorithm (2) to determine the resources necessary to perform such a task. Fujitsu researchers discovered that a fault-tolerant quantum computer (3) with a scale of approximately 10,000 qubits and 2.23 trillion quantum gates would be required to crack RSA -- well beyond the capabilities of even the most advanced quantum computers in the world today. Researchers further estimated that it would be necessary to conduct fault-tolerant quantum computation for about 104 days to successfully crack RSA .While the research reveals that the limitations of present quantum computing technology preclude the possibility of this threat in the short term, Fujitsu will conti...
