Breaking Encryption with a Quantum Computer Just Got 20 Times Easier

Breaking encryption with a quantum computer just got 20 times easier

A quantum computer with a million qubits would be able to crack the vital RSA encryption algorithm, and while such machines don't yet exist, that estimate could still fall further

The main novelty of Windows 11 is post-quantum encryption: for the first time, new quantum security algorithms can be used using standard Windows APIs. Microsoft has released post-quantum encryption (PQC) tools in advance access for Windows and Linux, allowing companies to test quantum-resistant security upstream of emerging threats. The update introduces NIST-standardized ML-KEM and ML-DSA algorithms for high-level threats.

Microsoft Adds Post-Quantum Cryptography to Windows Insider Builds and Linux - Quantum Computing Report

Microsoft has integrated post-quantum cryptographic (PQC) capabilities into both Windows Insider Canary Channel builds and Linux environments via its SymCrypt cryptographic library. This early-access release enables developers and organizations to evaluate the performance, compatibility, and deployment strategies of PQC algorithms in preparation for quantum-era threats. These updates are part of Microsoft's broader goal to support [...] The post…
