Businesses worldwide, especially those lagging in adopting quantum-secure measures, are urged to upgrade their encryption. Immediate strategic planning is recommended to ensure resilience against quantum threats as advancements continue to outpace initial projections. ## Content # Quantum Computers Pose Growing Threat to RSA-2048 Encryption Recent research from Google Quantum AI highlights that quantum computers, particularly those with a capacity of one million qubits, may soon be able to crack RSA-2048 encryption significantly faster than earlier estimates suggested. This revelation underscores the pressing need for organizations and enterprises worldwide to begin transitioning to post-quantum cryptography. ## Accelerated Threats from Quantum Advancements Quantum computing has witnessed rapid advancements in algorithms and error correction techniques, leading to an acceleration in the timeline for RSA-2048 encryption being compromised. Initial projections estimated that such encryption could only be broken with about 20 million qubits, but these current findings indicate that only one million qubits might be sufficient, potentially reducing the timeframe to as early as 2030. ## Urgent Need for Strategic Cryptographic Upgrades As quantum technology develops, there is a growing threat to existing encryption standards. Security experts emphasize the urgency for enterprises to adopt quantum-secure encryption to safeguard against imminent threats posed by quantum computers. Despite this urgency, many businesses, particularly in Germany, trail behind US companies in implementing these secure cryptographic measures. Enterprises are advised to proactively engage in cryptographic audits and strategic planning to ensure their systems are resilient against future quantum threats. Implementing comprehensive post-quantum cryptographic strategies now is imperative to avoid vulnerabilities that may arise in the future. ## Conclusion The ongoing advancements in quantum computing present significant risks to traditional encryption methods, including RSA-2048. Organizations must seriously consider these developments and take proactive measures to upgrade their cryptographic systems to ensure security in the quantum era. The time to act is now, as the technological evolution continues to compress the timeline for necessary security adaptations. ## Community discussion Top comments from developers on daily.dev. **@pkraszewski** · 0 upvotes > `RSA-2048` use is discouraged for quite some time. As of today, absolute minimum is `RSA-3072` and recommended is `RSA-4096`. If you are *stuck* with RSA that is. ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) · CNCF · 2 upvotes · 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) · CNCF · 1 upvotes · 0 comments --- Tags: [#cryptography](https://daily.dev/tags/cryptography), [#encryption](https://daily.dev/tags/encryption), [#quantum-computing](https://daily.dev/tags/quantum-computing), [#security](https://daily.dev/tags/security), [#tech-news](https://daily.dev/tags/tech-news) [View this post on daily.dev](https://daily.dev/posts/the-urgent-need-for-post-quantum-cryptography-rsa-2048-encryption-vulnerabilities-clffqlles) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"The Urgent Need for Post-Quantum Cryptography: RSA-2048 Encryption Vulnerabilities","url":"https://daily.dev/posts/the-urgent-need-for-post-quantum-cryptography-rsa-2048-encryption-vulnerabilities-clffqlles","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-urgent-need-for-post-quantum-cryptography-rsa-2048-encryption-vulnerabilities-clffqlles"},"datePublished":"2025-05-27T16:56:03.000Z","dateModified":"2026-03-15T03:49:17.041Z","description":"Research from Google Quantum AI highlights that quantum computers, with as few as one million qubits, may soon crack RSA-2048 encryption, suggesting...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2f89a73d334ad8fd503fd6b0347cbcd5?_a=AQAEuj9","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2f89a73d334ad8fd503fd6b0347cbcd5?_a=AQAEuj9","isAccessibleForFree":true,"articleSection":"Collections","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collections","logo":"https://media.daily.dev/image/upload/s--fk_6ycEi--/f_auto,q_auto/v1780996001/logos/collections?_a=BAMAMiWQ0","url":"https://daily.dev/sources/collections"},"commentCount":1,"discussionUrl":"https://daily.dev/posts/the-urgent-need-for-post-quantum-cryptography-rsa-2048-encryption-vulnerabilities-clffqlles","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":1}],"keywords":"cryptography,encryption,quantum-computing,security,tech-news","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collections","item":"https://daily.dev/sources/collections"},{"@type":"ListItem","position":3,"name":"The Urgent Need for Post-Quantum Cryptography: RSA-2048 Encryption Vulnerabilities"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/the-urgent-need-for-post-quantum-cryptography-rsa-2048-encryption-vulnerabilities-clffqlles","comment":[{"@type":"Comment","text":"RSA-2048 use is discouraged for quite some time.
