By the end of the decade, high-profile tech will be big.
Fujitsu's research shows there's no reason to panic about quantum computing's ability to decrypt encrypted data — which is unlikely anytime soon, the company said.
Fujitsu said it used a 39-qubit hardware quantum simulator to test how hard it would be for a quantum computer to crack data encrypted with RSA ciphers using Shor's algorithm.
The researchers calculated that hacking RSN would require a fault-tolerant quantum computer with 10,000 qubits and 2.23 trillion quantum gates, a far cry from the results of the quantum industry. IBM's Osprey quantum processor, announced last November, has 433 qubits.
Fujitsu said the researchers calculated that such a fault-tolerant quantum computer would have to work on the problem for 104 days to successfully crack RSA.
But before anyone gets too excited, IBM's Osprey Eagle processor has three times more qubits than last year, and the company announced in 2015 that by 2025 it's aiming for a 4158-qubit system. If you continue at the same pace. By the end of this decade, it could be 10,000 qubits.
While Fujitsu's research shows that the limitations of quantum computing technology could break existing encryption algorithms in the short term, the company says it will continue to evaluate the potential impact of ever more advanced quantum systems on encryption security.
“Our study shows that quantum computing does not pose an immediate threat to existing cryptographic techniques. Not even a negligible one.” .
"The world needs to prepare for the fact that one day quantum computers will fundamentally change the way we think about security."
The results will be presented this week at the 2023 Symposium on Cryptography and Information Security (SCIS 2023) in Kitakyushu, Japan.
IBM itself has warned of the dangers of the potential of quantum systems and published a report in this month's "Security in the Quantum Age" today, describing the need for "quantum-safe" methods. critical systems. The information. in the future
One of the concerns is that attackers are currently collecting and storing encrypted data that could still be used if quantum computers could crack the encryption used to protect them.
Last year, IBM released its z16 mainframe with support for "quantum-safe" algorithms in the Crypto Express 8S Accelerator subsystem.
Fujitsu presented a quantum simulator last year. At launch, the 64-node PRIMEHPC FX cluster will require the processing power of 700 servers capable of running 36-qubit quantum circuits, each based on the 48-core ARM-A64FX chip Fugaku Supercomputing used in the system. .
The company plans to boost the simulator's performance to 40 qubits by April. The company plans to build its own 64-qubit quantum computer in collaboration with the RIKEN Research Institute. ®
