The race to useful quantum advantage - covering the hardware, algorithms, and milestones that matter.
Jülich inaugurated a trapped-ion machine, RIKEN put an SDK into operation, and Hartree announced a simulator-backed demonstrator. The three milestones are different.
D-Wave, Rigetti, Quantinuum and PsiQuantum take different routes to a quantum computer. The award descriptions Commerce published name the same manufacturing problems.
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.
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.
Joint engineering is underway. No volumes, economics, dates, or component assignments disclosed. The IPO prospectus already named Quanta Computer a partner.
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.
July brought integrated cryogenic control and new process-development commitments. HRL's chip can host 18 qubits, but its largest published circuit used seven.
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.
Quantinuum's result demonstrates a universal topological gate set on conventional qubits, while the resource advantage that matters remains unproven.
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.
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.
