Jülich, RIKEN and Hartree Show Different Stages of Quantum-Supercomputer Integration
Jülich inaugurated a trapped-ion machine, RIKEN put an SDK into operation, and Hartree announced a simulator-backed demonstrator. The three milestones are different.
Japan's Shunkai Project Sets a 10,000-Physical-Qubit Goal for 2031
IMS says its neutral-atom system will begin at approximately 50 qubits and scale to 500. Its March 2031 goal: 10,000 physical qubits with error detection and correction, no logical-qubit count.
Europe Is Sorting Quantum Hardware by Funding Instrument, Not Just Qubit Type
EuroHPC's six August quantum actions continue partnerships selected in 2022. The EU's platform-assessment roadmap is still a draft and is open for public comment.
Quantinuum Formalizes Quanta Manufacturing Partnership, but Production Terms Remain Undisclosed
Joint engineering is underway. No volumes, economics, dates, or component assignments disclosed. The IPO prospectus already named Quanta Computer a partner.
Quantum Computers Are Moving On-Premises. The Deals Are Not All the Same.
A six-qubit ESA testbed, a 150-qubit EuroHPC purchase, a neutral-atom roadmap in Illinois and an NSF-funded integration platform share a location strategy, not a common level of readiness.
Silicon spin gains manufacturing evidence while demonstrated scale stays small
July brought integrated cryogenic control and new process-development commitments. HRL's chip can host 18 qubits, but its largest published circuit used seven.
SaxonQ tells SCN a demo SXQ128 is in setup, with first 8-qubit coupled-NV delivery due this quarter
In written responses, CEO Marius Grundmann says the cores are not entangled and details the estimates behind SaxonQ's six-to-ten-times energy claim.
The Incredible Shrinking Qubit Count: What Oratomic's $300M Neutral-Atom Bet Is Wagering On
On paper, the qubits to break RSA-2048 fell from a million to tens of thousands in a year, but the smaller machines trade the saving for weeks of runtime. Oratomic raised $300M to build one.
The Hardest Pieces of Fusion's Fuel Chemistry Ran on a Quantum Computer. The Weakest Link Is Now Classical.
ORNL, Cleveland Clinic, and IBM computed nine FLiBe configurations on quantum hardware. The quantum solver hit its marks; the workflow around it is now the bottleneck.
DOE Wants Fault-Tolerant Quantum by 2028. The Roadmaps Show How Hard That Target Is to Define.
Logical qubit' means something different on every vendor roadmap, and DOE's 2028 target doesn't yet say which one counts. A 90-day specifications release this fall settles it.
Microsoft Pulled Its Quantum Timeline to 2029. Physicists Are Still Asking Whether It Has Demonstrated the Qubit
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 Discloses $10 Billion Quantum Investment Plan as 2029 Fault-Tolerance Target Comes Into Focus
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.
