Above: China gets the logic right in quantum silicon chips.
This Quantum Computing Weekly Round-Up captures a week full of momentum as governments, companies, and researchers push quantum tech into practical territory. Whether it’s beefing up security ahead of quantum threats or unlocking new simulation power, the pieces are falling into place faster than ever.
The cybersecurity crowd at RSAC is clearly quantum-aware. Swissbit is positioning itself for post-quantum hardware authentication, while ZeroTier dropped ZeroTier Quantum — the world’s first end-to-end quantum-secure networking platform. Dell Technologies outlined expanded protections for the AI era that also tackle emerging quantum risks. Forbes Tech Council made the case for data centers needing quantum security just as urgently as reliable power.
Public money is flowing. Australia’s National Reconstruction Fund committed $20 million to Silicon Quantum Computing and atomic-scale semiconductor work. Karnataka, India launched a major quantum mission with a ₹1000 crore ($114 million) fund aimed at a $20 billion quantum economy by 2035 via Quantum Computing Report. Connecticut celebrated the launch of its Quantum Workforce Hub, and Ireland deployed its first QKD network thanks to the Walton Institute at SETU and QBird.
Real-world use cases are accelerating. Q-CTRL and Anello Photonics teamed up to create resilient navigation for UAVs in GPS-denied environments. Britain is running world-first quantum navigation trials on mainline rail, according to Rail Technology Magazine. SBQuantum and Spire will send a quantum diamond magnetometer to orbit.
Technical progress keeps coming. Memsstar’s ORBIS Alpha Etch System landed at TUM’s Quantum Networks Lab. Google detailed advances in neutral-atom quantum computers. UCF researchers made strides on scalable entanglement. Fujitsu and University of Osaka developed tech that slashes resource needs for chemical energy calculations on early fault-tolerant quantum computers. A Chinese silicon quantum processor achieved logical operations, reported by The Qubit Report.
IBM’s quantum hardware accurately simulated real magnetic materials. Conductor Quantum launched CODA MCP to better fuse quantum tools with AI agents. Rigetti plans a $100 million UK investment. Xanadu closed its business combination. QuiX Quantum named Robin Wittland as Chief Commercial Officer.
Deployment talk is heating up. QuSecure explored post-quantum cryptography for banking under the SEC framework. SEALSQ highlighted its post-quantum chips for smart meters. The Ethereum Foundation launched a quantum PQC security hub. Google shared its cryptography migration timeline and PQC migration plans.
