The article centers on the computational requirements for quantum computers to break RSA encryption, specifically analyzing the gap between current NISQ-era hardware and the million-qubit threshold needed for a cryptographic threat. It highlights the critical role of error correction in extending the timeline for viable attacks while addressing the urgency of "Harvest Now, Decrypt Later" strategies.

A million qubits needed to crack RSA encryption, says new AIQLAB report

Quantum ZeitgeistOctober 14, 20265 min read

According to estimates from 2025, breaking a commonly used RSA key would require a machine with a number of qubits on the order of a million.

According to estimates from 2025, breaking a commonly used RSA key would require a machine with on the order of a million qubits. The report explains that while NISQ (Noisy Intermediate-Scale Quantum) computers, ranging from a few hundred to a few thousand qubits, are limited by “noise” and short calculation windows, combining multiple physical qubits into one logical qubit is essential for error correction. This means current machines do not pose an immediate threat, but achieving truly secure quantum computing requires significant hurdles to be overcome. The vulnerability stems from the potential…
