News Summary: NVIDIA researchers are using JUPITER — the largest supercomputer in Europe, built at Jülich Supercomputing Centre — for a record-breaking fault-tolerant quantum computing simulation.
The 104-qubit simulation is the largest comprehensive simulation of a fault-tolerant quantum computing system to date, with no prior simulations modeling quantum processors in such full detail.
Running on a system of NVIDIA GH200 superchips at Jülich Supercomputing Centre, the 104-qubit simulation is the largest comprehensive simulation of a fault-tolerant quantum processor to date, modeling how a realistic quantum processor performs fault-tolerant computation at record scale.
Computing in the presence of such noise — known as fault-tolerant quantum computing — requires the use of magic states, a specific arrangement of qubits that is continually consumed during a fault-tolerant quantum computation.

Polish deep-tech startup finQbit is building next-generation hybrid quantum and AI infrastructure to solve one of banking's most persistent bottlenecks: financial risk modeling and derivative pricing.
Founded in 2023 by banking veterans Tomasz Ćwik and Rafał Pracht, the company has raised over $2 million USD in funding and grants to date, established a 10-person operating team, and signed its first commercial contracts.
Crucial to finQbit's early journey was its participation in the 28DIGITAL (formerly EIT Digital) programme, which provided essential R&D funding, incubation support, and early-stage backing from the very start.
Building on that foundation, finQbit in September announced major strategic milestones: securing investments from MB SpeedUp, the joint venture set up between Mediobanca and the London-based company builder and early-stage investor Founders Factory, and welcoming former PKO Bank Polski CEO Zbigniew Jagiełło to its advisory board.

Zakura, a developer of Zcash full node software, has proposed a way to stop a future quantum computer from linking users' private Zcash payments, in an engineering post by Zakura developer Adam Tucker announced on Sunday.
The approach needs no network upgrade, Zakura said in a tweet introducing what it called "post-quantum unlinkable swaps for Zcash."
Each swap out of ZEC writes one of the user's shielded addresses to NEAR's public chain as a refund address, whether or not a refund is ever made.
Zakura's fix derives a separate incoming viewing key for each address that has to be published, while leaving the account's spending key untouched.
"If a quantum computer ever breaks a posted swap address, it will not be able to link this to any other transaction," Tucker wrote in a Twitter thread.

Nvidia’s quantum computing marketing leader Nicholas Harrigan described a useful quantum computer as an AI supercomputer with quantum hardware integrated into it: “The kinds of workloads you want to run on that device are hybrid.
AI accelerates quantum development AI is also accelerating quantum development on two fronts, Harrigan said: “One is that we can make the hardware that we use for quantum computing better.
“Supercomputers are part of quantum computing infrastructure, but access to them is not trivial,” said Harrigan.
Financing commercial adoption There are significant costs associated with new hardware technology such as quantum computing.

Keeping silicon quantum bits accurate while they work together could help turn established chipmaking technology into larger quantum computers capable of tackling increasingly complex problems.
Silicon spin qubits offer that possibility, but the precision they achieve on their own can slip when several are controlled at once.
In silicon spin qubits, information is encoded in the spin of an electron trapped in a silicon substrate.
Fidelity measures how accurately a quantum operation is performed.
With the new protocol, fidelities stayed above 99.99% when up to three qubits operated at the same time.

In tests involving Gaussian boson sampling, classical computers using the algorithm matched or exceeded the performance of some current quantum devices.
PRESS RELEASE — Researchers have developed an algorithm that enables off-the-shelf computers to run quantum simulations previously only possible using the world’s most powerful supercomputers.
Key to informing the creation of bigger, more reliable quantum computers is the development of algorithms to simulate how devices might work in reality.
The work could aid the development of light-based quantum devices, one of several branches of current quantum research by academics and industry, the team says.
This could allow scientists to simulate photonic quantum computers in unprecedented detail, the team says.

But a future quantum computer could theoretically exploit a small gap in NEAR Intents, a cross-chain swapping service, to connect a user’s private ZEC transactions to their wallet, undermining that privacy.
In a new engineering post, it proposed giving every ZEC swap made through NEAR Intents its own private key.
The change would close a gap that a future quantum computer could use to piece together a user’s payment history.
When someone swaps private ZEC for USDC through it, the service posts one of their private Zcash addresses on NEAR’s public chain, so it knows where to send back any unused ZEC.
As such, no quantum computer has been demonstrated that can recover these keys.

The 60-page audit found widespread failures to identify vulnerable cryptographic systems, develop reliable funding estimates, and test replacement technologies.
The results showed that only one agency had fully developed a prioritized inventory of vulnerable cryptographic systems.
The shortcomings extended to the information agencies maintained about their own technology.
Without this information, agencies cannot reliably identify which technologies must be upgraded, which require replacement, or how to prioritize systems containing sensitive information.
It directs agencies to prioritize high-impact systems, high-value assets, sensitive information, and cryptographic access controls.

Quantum computers, by contrast, use "qubits".
However, current quantum computers have major flaws.
But quantum computers are superpositions of all possible outcomes, so they must include all operations for both Route A and Route B in every single run.
An automatic evaluation program checked the correctness of the design and gave it a "score" (number of qubits used × number of quantum gates).
But quantum computers cannot discard drafts!

Quantum execution platform Open Quantum (developed by Quantum Rings in partnership with qBitTensor Labs) has released a native software integration for Qrisp, an open-source, high-level quantum programming language maintained under the Eclipse Foundation in collaboration with Fraunhofer FOKUS.
Available via Python package managers (pip install "openquantum-sdk[qrisp]"), the plugin allows developers to compile and execute high-level Qrisp programs directly on physical quantum processing units (QPUs) from IonQ, Rigetti Computing, IQM Quantum Computers, and AQT without writing vendor-specific gate-level code or altering algorithm logic.
The Open Quantum Qrisp plugin interfaces directly with native execution routines (QuantumVariable.get_measurement and QuantumCircuit.run), providing single-string backend switching across both trapped-ion and superconducting architectures.
It also complements Qrisp’s recognition at the Quantum Effects Awards 2026, as well as IQM’s contributions to open-source QAOA libraries and Resonance cloud QPU infrastructure.

The European Quantum Industry Consortium (QuIC) has published a position paper titled “Optimising Dual-Use Controls for European Quantum Technologies,” addressing the European Commission’s open consultation on the evaluation of the EU Dual-Use Regulation (Regulation (EU) 2021/821).
Following the November 2025 integration of quantum computers, cryogenic amplifiers, and wafer probers into Annex I of the EU dual-use control list, QuIC warns that fragmented national implementation across the 27 EU Member States is imposing severe administrative friction, delayed shipments, and lost international revenue for European startups and scale-ups.
Coordinated by lead authors David Morcuende (QuIC) and Ulrich Mans (QuantWare)—with contributions from industry leaders including Pasqal, planqc, IQM, Qblox, Bluefors, Qilimanjaro, and Indra—the paper emphasizes that export controls must align with the upcoming EU Quantum Act to ensure European commercial competitiveness without introducing uncoordinated trade barriers.

The scoring metric was the number of qubits occupied multiplied by the number of quantum gates.
On classical computers, this operation is typically performed using the divsteps algorithm, but that algorithm has never been successfully ported to quantum circuits.
Rebuilding Google's algorithm architecture The second major breakthrough came in the quantum optimization algorithm DQI (Decoded Quantum Interferometry).
After analysis, Claude determined that this algorithm was mismatched with the operating model of quantum circuits and decisively replaced the core engine with the Berlekamp-Massey algorithm.
The significance of this discovery extends beyond mere algorithm optimization.
