A recent study indicates that advances in quantum computing could soon undermine the RSA-2048 encryption standard, which secures sensitive web and financial transactions. Researcher Craig Gidney estimates that a quantum computer with under a million noisy qubits could factor a 2048-bit RSA integer in less than a week. This highlights the critical need for organizations to transition to quantum-resistant encryption standards. The Post-Quantum Cryptography Coalition (PQCC) has recommended a roadmap for this transition, with deadlines tied to regulatory pressures, especially in the finance sector, to ensure data security against future quantum threats.
I estimate that a 2048 bit RSA integer could be factored in less than a week by a quantum computer with less than a million noisy qubits.
The fact that RSA-2048 encrypted data can be cracked in a week means that once such systems are available, hackers would be able to decrypt stolen data.
