French Startup C12 Unveils Four-Generation Roadmap to 100,000-Qubit Fault-Tolerant Quantum Computer by 2033 Using Carbon Nanotube Spin Qubits
Paris-based C12 published a four-stage plan to scale its carbon nanotube spin-qubit processors from 16 physical qubits in 2027 to over 100,000 by 2033, betting a solid-state modality can catch incumbents on error-corrected quantum computing.
Rigetti Launches 108-Qubit Cepheus System, the Largest Modular Chiplet-Based Quantum Computer Available via the Cloud
Rigetti Computing has made its 108-qubit Cepheus-1-108Q system generally available through its own cloud platform and Amazon Braket, marking the first gate-based quantum processor exceeding 100 qubits on AWS.
India's National Quantum Mission Reaches 1,000-Kilometer Secure Communication Milestone Ahead of Schedule, Powered by Indigenous QKD Technology
India's National Quantum Mission has demonstrated a 1,000-kilometer quantum-secured communication network using QNu Labs' indigenous ARMOS QKD platform, reaching the halfway mark of its 2,000 km target in under two years — well ahead of the original eight-year timeline.
Innsbruck and Aachen Researchers Demonstrate First Measurement-Free Fault-Tolerant Quantum Algorithm, Running Grover's Search on Three Logical Qubits
A European team eliminates mid-circuit measurements from fault-tolerant quantum computing, running Grover's algorithm on three logical qubits encoded in eight trapped ions without pausing to read error syndromes.
Quantum Corridor Deploys First Quantum Computer on North America's Only Interstate Quantum-Safe Commercial Network
Quantum Computing Inc. installed its Dirac-3 quantum optimization machine on the Quantum Corridor network connecting Chicago and Hammond, Indiana, marking the first time a quantum computer has been deployed on a QKD-secured commercial fiber network spanning U.S. state lines.
Google Quantum AI Demonstrates 20-Fold Reduction in Qubits Needed to Break Elliptic Curve Cryptography, Accelerating Post-Quantum Migration Timeline
A Google Quantum AI whitepaper shows fewer than 500,000 qubits could break elliptic curve cryptography in minutes, a 20-fold improvement over prior estimates that accelerates the post-quantum migration timeline.
Oratomic Launches With Caltech Research Showing Shor's Algorithm Is Feasible With Just 10,000 Neutral-Atom Qubits
A Caltech-backed startup claims utility-scale quantum computers need far fewer qubits than previously estimated, potentially accelerating the timeline for cryptographically relevant machines to the end of the decade.
Turing Award Goes to Quantum Science for the First Time as Bennett and Brassard Win Computing's Highest Honor
Charles H. Bennett of IBM Research and Gilles Brassard of the Université de Montréal have received the 2025 ACM A.M. Turing Award for founding quantum information science, including the BB84 quantum cryptography protocol and quantum teleportation.
Xanadu Clears Final Shareholder Vote to Become the First Publicly Traded Photonic Quantum Computing Company
