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.

IonQ linked two trapped-ion quantum systems via photonic entanglement in a first for commercial quantum computing, and won a DARPA contract to extend the approach across multiple qubit types.

Nvidia's new Ising family targets quantum error correction and calibration, claiming 2.5x faster and 3x more accurate decoding than the current open-source standard, with more than 20 labs and hardware makers already on board.

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.

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 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.

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.

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.

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.

Broadcom announced the first end-to-end post-quantum cryptography-safe in-flight network encryption solution for Fibre Channel storage, shipping over 120,000 adapters as NIST sets a 2030 deadline to deprecate RSA and enterprises race to counter harvest-now-decrypt-later attacks.

Crane Harbor shareholders approve SPAC merger with Xanadu Quantum Technologies, clearing the way for a $3.6 billion Nasdaq and TSX listing under ticker XNDU on March 27.

2026 marks the transition from noisy quantum experiments to error-corrected commercial systems, with neutral atom platforms from QuEra, Atom Computing, and Pasqal leading the charge.
