What’s Happening in Quantum — and What It Means
Fault-Tolerant Quantum Computing (FTQC) with Erasure Qubits
Fault-tolerant quantum architectures based on erasure qubits represent an exciting development in quantum engineering. They blend clever hardware design with advanced error-correcting codes to tackle the Achilles’ heel of quantum computers: noise. The research by Gu, Retzker, and Kubica shows that by making qubits a ...
Zuchongzhi 3.0 Quantum Chip: Technical Analysis and Implications
China’s quantum computing powerhouse, the Zuchongzhi research teams, just unveiled Zuchongzhi 3.0, a new superconducting quantum processor with 105 qubits, marking a major leap in quantum computing performance. Announced in March 2025 by a University of Science and Technology of China (USTC) team led by ...
AWS Announces Ocelot Chip for Ultra-Reliable Qubits
Amazon Web Services (AWS) has officially unveiled Ocelot, its first in-house quantum computing chip, marking a significant milestone in the company’s quantum ambitions. Announced on February 27, 2025, Ocelot is a prototype processor designed from the ground up to tackle quantum error correction in a ...
PsiQuantum Demonstrates Foundry-Manufactured Photonic Quantum Computing Platform With Record Fidelities
PsiQuantum publishes the first complete photonic quantum computing platform fabricated in a commercial semiconductor foundry, with record fidelities across every building block ...
QuantWare unveils Contralto‑A, a QPU designed for quantum error correction experiments
QuantWare has introduced Contralto‑A, a new superconducting quantum processing unit aimed specifically at advancing practical quantum error correction (QEC) development. Announced in Delft, The Netherlands, the processor is positioned for teams working on surface-code style QEC demonstrations and early fault‑tolerance roadmaps. According to the company, ...
Silicon Runs Its First Real Algorithm: Grover’s Search on Four Qubits With Every Gate Above Threshold
24 Feb 2025 - There is a difference between proving you can throw a ball and proving you can play a game. For three years, silicon spin qubits have been proving they can throw: individual gate operations above the fault-tolerance threshold, entanglement between pairs and ...
Microsoft’s Majorana-Based Quantum Chip – Beyond the Hype
In February 2025, Microsoft unveiled “Majorana 1,” an eight-qubit quantum chip built on a topological qubit architecture – a first-of-its-kind design leveraging exotic Majorana quasiparticles. This chip uses a new material called a “topoconductor” (a specially engineered topological superconductor) made from indium arsenide and aluminum, ...
Germany’s BSI Draws the Sharpest PQC Migration Lines in Europe: 2030 for Critical Infrastructure, 2032 for Everyone Else

South Korea Selects Four Domestic PQC Algorithms, Running a Parallel Track to NIST
South Korea has selected four domestic PQC algorithms through its KpqC competition, none of which are NIST standards. The choice to run a parallel standardization process alongside NIST adoption raises interoperability questions that multinationals cannot ignore ...
The EU’s Cyber Resilience Act Doesn’t Say “Post-Quantum” but Its Crypto-Agility Requirement Will Shape PQC Migration
The EU Cyber Resilience Act doesn't mention "post-quantum" by name. But its requirement that products support cryptographic updates throughout their lifecycle effectively mandates the architectural capability that PQC migration depends on: crypto-agility ...
Executive Order 14144: Biden’s Big Swing at Cybersecurity Modernization
On January 16 2025 President Joe Biden signed Executive Order 14144, “Strengthening and Promoting Innovation in the Nation’s Cybersecurity.” The 17‑page directive is the administration’s most comprehensive cyber policy since EO 14028 in 2021 and, for the first time, embeds post‑quantum cryptography (PQC) migration deadlines directly in federal law. At its ...
Bank of Israel Tells Banks: Map Your Cryptographic Exposure and Submit Quantum Preparedness Plans Within a Year
The Bank of Israel's Banking Supervision Department has issued a directive requiring every banking corporation to map its cryptographic exposure, assess quantum risks, and submit a formal preparedness plan within one year. Among the earliest binding financial-sector directives globally ...
NIST Releases NIST SP 800-227 IPD
NIST has just released the initial public draft of CSWP 48, part of its Migration to Post-Quantum Cryptography project: "Mappings of Migration to PQC Project Capabilities to NIST Cybersecurity Framework 2.0 and to Security and Privacy Controls for Information Systems and Organizations." ...
First Successful Factorization of RSA-2048 by Quantum Computer? Not Even Close!
Chinese researchers published “A First Successful Factorization of RSA-2048 Integer by D-Wave Quantum Computer.” To get straight to the point - the title is misleading. The authors did NOT factor a general RSA-2048 key (as used in real cryptography); instead, they factored a specially structured ...
Google AI’s Surface Code Breaks the Quantum Error Threshold
In a landmark experiment, Google Quantum AI researchers have demonstrated the first quantum memory operating below the error-correction threshold on a superconducting processor. Using two new “Willow” quantum chips of 72 and 105 qubits, the team ran surface code error-correction cycles that actually outperformed the ...
