Fujitsu assesses vulnerability of RSA encryption to potential quantum computer threats

Jan, 23, 2023 Hi-network.com

Japanese ICT company Fujitsu announced that it had conducted successful trials to evaluate the widely-used RSA encryption 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. Fujitsu researchers discovered that a fault-tolerant quantum computer with a scale of approximately 10,000 qubits and 2.23 trillion quantum gates would be required to crack RSA, which is much higher than current quantum computing capacities.
