Will Quantum Computing Break RSA-2048 Encryption by 2030?

‘Harvest now, decrypt later’: Hackers steal data they can’t read—banking on quantum to crack it – Worldpostone

Hackers are already collecting and storing unencrypted data to be decrypted later by quantum computers, a practice called “harvest now, decrypt later,” as quantum-enabled decryption could unlock financial and personal data in the future, with experts like Nicolas Sauvage predicting meaningful protection may still be years away.

Quantum Computers Could Wipe Out 30% of Bitcoin. XRP Says Only 0.03% of Its Supply Is at Risk - 24/7 Wall St.

Bitcoin’s publicly exposed supply is about 30% of issued BTC with debates over whether it’s realistically exploitable, while XRP’s dormant-exposed supply is about 0.03% (roughly 21 million XRP) per an independent audit; quantum-risk mitigation plans for Bitcoin (BIP-361/360) face uncertain activation dates (potentially Jan 1, 2027) and Ripple’s four-phase post-quantum roadmap aims for full network-wide post-quantum signatures by 2028, with XRPL testing of post-quantum schemes already underway on a Devnet.

Google Sets 2029 Target to Migrate to Post-Quantum Cryptography - BitRss - Crypto World News

Google announced a 2029 target to migrate to post-quantum cryptography to counter threats from quantum computing, including store-now-decrypt-later attacks and risks to digital signatures, signaling urgency for widespread cryptographic upgrades across crypto, finance, and tech sectors.

Quantum computer majorana 2 microsoft trump eo – Breaking News & Latest Updates 2026

The article reports on ongoing hype and progress in quantum computing, highlighting Microsoft’s Majorana 2 chip and its contested claim to accelerate scalable quantum computing by 2029, alongside competing bets and funding from IBM, Google, Quantinuum, and the Trump administration, while noting persistent challenges with qubit errors and the steady advance of quantum error correction toward practical, large-scale, logical qubits by the end of the decade.

The CMMC Pause Won't Change The Quantum-Security Deadline | Alpha Leaders

The article explains that in 2026 the White House issued two quantum-related directives—EO 14413 accelerating quantum tech and EO 14412 mandating post-quantum cryptography by 2030 for key establishment and 2031 for digital signatures—while the CMMC pause shifts compliance measurement from paperwork to engineering but does not drop the obligation to protect federal data, signaling that the cryptographic migration deadline remains urgent even as the certification regime is temporarily relaxed.

Google Quantum Breakthrough Sparks Renewed Urgency for Post-Quantum Migration in Crypto - BitRss - Crypto World News

A Google Quantum AI paper suggests breaking 256-bit ECDLP could become feasible with roughly 1,200–1,450 logical qubits and 70–90 million Toffoli gates, prompting rapid, open community optimizations to elliptic-curve cryptography, renewed urgency for post-quantum migration across crypto ecosystems (notably Ethereum and Bitcoin), and a shift from panic to proactive planning for upgrades, asset protection, and governance.

Nations at the Quantum Table

Major governments are rapidly turning quantum tech into policy and procurement: the US is pairing about $2B CHIPS Act funding with executive orders on quantum security; the UK added £2B to its National Quantum Strategy and launched ProQure; Japan backed roughly ¥1.05T in 2025–26 for industrialization; Canada integrated quantum into defence with over $900M and launched the Quantum Defence Innovation Secure Hub in Calgary; Singapore announced a S$37B RIE 2030 plan prioritizing quantum and hosting Quantinuum’s Helios; the Netherlands aims for a top-three global quantum position by 2035 with €2B in public-private investment; Israel initiated a national quantum platform under Project Nexus; and broader moves include national sovereignty, defence applications, and rapid scaling of quantum capabilities across multiple countries.

CSA Guides Singapore’s Infrastructure Toward Quantum Safety

The Cybersecurity Agency of Singapore (CSA) is steering national infrastructure toward quantum-safe security, mandating by March 2027 migration plans for Critical Information Infrastructure (CII), aiming for full system migration by 2031, using the Quantum Readiness Index to assess five domains (risk, governance, technology, training, external engagement) and aligning with international standards while enforcing gradual implementation through planned upgrades and vendor collaboration.

US Treasury launches quantum-readiness task force to protect financial systems

The U.S. Treasury has formed a Quantum-Readiness Task Force to guide the financial sector’s switch to post-quantum cryptography, with three workstreams (sector alignment, vendor readiness, and digital assets risks) and concrete deadlines (sensitive systems by 2030, digital signatures by 2031), building on NIST standards and the G7 roadmap to treat quantum threats as a systemic risk.

GSA, Treasury kick off post-quantum initiatives to protect against cyber threats | Federal News Network

The GSA is updating FICAM architecture and expanding a testing lab to support quantum-resistant and crypto-agile security for federal access systems, while Treasury launches a Quantum-Readiness Task Force to accelerate the financial sector’s shift to post-quantum cryptography, both building on President Trump's June executive orders and OMB’s guidance requiring agencies to develop PQC migration plans and pilot early migrations through 2030-2031.
