The race to useful quantum advantage - covering the hardware, algorithms, and milestones that matter.
Majorana 2 halves Microsoft's timeline to a scalable machine and reports a 20-second parity lifetime. The preprint measured one observable on one nanowire, unreviewed; critics say that is not yet a demonstrated topological qubit.
IBM told investors it plans to spend more than $10 billion on quantum over five years. Annualized, that is roughly twice the U.S. federal QIS R&D budget, but the figure is a blended forward-looking plan, not a booked balance-sheet item.
Commerce signed nine LOIs worth $2.013 billion to anchor a U.S. quantum supercomputing supply chain. Two foundry models funded in parallel, federal equity in every recipient.
An arXiv preprint shows single-molecule ODMR in a designer carbene with 2.2 ms coherence at 4.5 K. Two days later, NVision announced a $55 million Abbott-led round and a photonic molecular-qubit architecture still demonstrated at just one emitter.
Quantinuum's H2 trapped-ion processor claims quantum magnetism simulation beyond classical tensor network reach. Materials science utility undemonstrated.
Cisco's research prototype and DARPA's 19-team backbone program together define what the first-generation network layer of a quantum-classical hybrid actually looks like, and what still doesn't work.
DARPA's new HARQ program funds 19 teams to build a heterogeneous quantum computer that mixes trapped-ion, neutral-atom, superconducting, and diamond qubits over a shared photonic backbone, targeting a 1,000x cut in physical resource demand.
The World Quantum Day launch adds open models for calibration and QEC decoding, but the bigger move is NVIDIA tying AI inference to CUDA-Q, CUDAQ-Realtime, and NVQLink in the path to fault tolerance.
Led by imec and backed by the Chips Joint Undertaking, SPINS aims to prove that semiconductor fabs, not research labs, are where quantum computing finally scales. Ten countries and three silicon platforms, all betting on spin.
Phantom codes, QLDPC codes, iceberg codes, cat qubits, neural decoders. Five years ago, surface codes were the only game in town. Now there's a genuine competition, and it might get us to fault tolerance faster than any single approach could.
The first pure-play quantum computing company to cross $100M in annual revenue just spent $1.8 billion acquiring a semiconductor foundry. That tells you where quantum is heading.
