FROM THE EDITOR.

First some congratulations to ColibriTD. The team reported it has raised a €4 million seed round.

The company said the funding will support research and development, as well as the hiring of quantum researchers and engineers. ColibriTD also plans to expand its partnerships with hardware companies, academic institutions and industry groups.

The round is another sign that investors remain willing to back companies developing practical software for quantum and hybrid computing.

Private funding is only one part of the picture. Public monies are still backing quantum, too.

This week, the U.S. National Science Foundation this week awarded more than $290 million to eight Quantum Leap Challenge Institutes working across quantum computing, sensing, networking and simulation.

Each institute will receive roughly $28 million to $37 million over five years. The research will cover fault-tolerant computing, quantum error correction and other technologies needed to make quantum systems more useful and reliable.

The program also brings together researchers from 36 higher-education institutions across 19 states, federal agencies and more than 30 companies.

This continues to be a global effort. Japan, for example, offered a reminder that national quantum plans ultimately have to produce operating systems.

Japan’s Institute for Molecular Science reported that it has begun operating Shunkai, the country’s first full-stack neutral-atom quantum computer. The system initially has about 50 qubits and was developed with Hitachi and Infleqtion.

Shunkai is expected to scale to about 500 qubits before eventually reaching 10,000 physical qubits with error-correction capabilities by March 2031. Those targets remain ambitious, but the project has so far made steady progress in line with its development timeline.

Have a great weekend, and thanks for reading!

INSIDER BRIEF.

— Krista Elliott, Narrative Content Strategist at The Quantum Insider

Check out this week’s handpicked quantum research studies and news focusing on real-world impact: improving accuracy, reducing latency, using fewer resources, or solving problems that classical methods struggle with.

  • A team led by Boston College physicist Brian Zhou developed a spin transistor, a single device that both computes and stores data, using an atomically thin magnetic semiconductor called chromium sulfur bromide (CrSBr). To see how the device actually behaves at the nanoscale, the team built a single-spin quantum microscope using scanning nitrogen-vacancy (NV) center magnetometry, a quantum sensing technique that maps magnetic fields by tracking a single atomic defect. That imaging revealed an electrical on/off ratio of a million percent and a magnetic on/off ratio of 3,000%, the latter notably higher than earlier efforts.

  • Researchers from the University of Padua, ThinkQuantum, and Italy's National Research Council demonstrated quantum key distribution (QKD) across an 18-kilometer free-space link in northeastern Italy, then fed the signal directly into standard fiber-optic cable for the final stretch to the receiver. The system generated secret encryption keys at about 1,000 bits per second using high-efficiency superconducting detectors, and about 200 bits per second using cheaper, room-temperature detectors.

  • A Caltech-led collaboration, combining the experimental group of physicist Manuel Endres with the theory group of Jason Alicea, along with theorists from Université Paris-Saclay and the Technical University of Munich, used a neutral-atom quantum simulator to directly measure energy levels predicted by two conformal field theories for the first time. Using a new technique called many-body modulation spectroscopy, essentially gently shaking the entire atom chain at chosen frequencies and measuring the response, the researchers mapped out a ladder of energy levels matching predictions from the Ising and tricritical Ising conformal field theories, theories that have stood untested experimentally for roughly 40 years.

Quantum Headlines.

The very last item on my list this week is actually the one that piqued my interest the most. A Finish game studio, MiTale, is exploring with simulations how quantum computing could help with foundational work like story dynamics, environment generation, and selected visual effects. The idea is to “enhance player-centered design practices to provide truly unique experiences in each gameplay session.” The game’s website goes on to say, “In collaboration with experts from IBM Quantum Computing, we aim to utilize quantum computer in building the the world and narrative that the player inhabits according to the quirks of a malfunctioning AI, making every gameplay unique! This is the first commercial game on the market utilizing quantum computing into an immersive narrative experience.”

I started off playing an Atari 6400 way back in the ‘80s. My eldest is hoping to go into game development as a career. And it’s incredibly cool to think about how quantum technology is going to push gaming even further into the immersive art form it’s become.

China has named quantum technology as a priority frontier field in a new 2026-2030 plan aimed at strengthening the country’s cybersecurity and information technology industries. The plan also targets advances in high-end chips, software, AI, cybersecurity, blockchain, brain-computer interfaces and other strategic technologies. The document does not specify quantum-related funding, technical milestones or which areas of quantum computing, communications or sensing will receive priority.

The U.S. Treasury launched a Quantum-Readiness Task Force to coordinate the financial sector’s transition to post-quantum cryptography and prepare for future quantum-related cybersecurity risks. The public-private initiative will focus on sector-wide PQC transition, third-party and vendor readiness, and risks involving digital assets and emerging technologies. The task force will bring together government, financial institutions, market infrastructure operators and technology providers to address critical dependencies, cryptographic agility, interoperability and operational resilience.

The Quantum Datacenter Alliance will hold its second international forum Oct. 1 in London, bringing quantum and data center leaders together to address the challenges of building utility-scale distributed quantum computers. The forum will focus on system-level issues including quantum processors, networking, error correction, interoperability, middleware, software, algorithms and integration with classical computing infrastructure. Speakers will include executives and technical leaders from Atom Computing, QuEra, NVIDIA, IBM, Q-CTRL, Nu Quantum, Quantinuum and other organizations across the quantum computing ecosystem.

Sweden has launched its first national quantum technology strategy, setting goals through 2036 for research, industry, talent, security and international cooperation. The plan highlights Sweden’s strengths in quantum computing while calling for better coordination, more skilled workers and improved financing for quantum startups and commercialization. The strategy also urges early adoption of quantum-safe cybersecurity measures, including post-quantum cryptography, to address future threats to current encryption.

GLOBAL QUANTUM + AI CHALLENGE!

The Global Quantum + AI Challenge is an international initiative designed to move quantum research closer to industrial use. In partnership with enterprises, technology providers, startups, and research teams, the program focuses on real-world problems where quantum computing may eventually create practical value, with AI and high-performance computing serving as key tools for testing, benchmarking, and deployment.

This week’s featured challenge comes from Airbus, which is seeking new approaches to predictive aerodynamic modeling. Accurately forecasting aerodynamic flows requires solving partial differential equations using state-of-the-art HPC, but current methods still face scaling limits and continued reliance on expensive wind tunnel testing under demanding acceleration and Mach conditions. Airbus is looking for more efficient PDE solvers that could help future product solutions meet strict quality, performance, and environmental requirements.

Teams working in quantum algorithms, hybrid quantum-classical workflows, scientific machine learning, computational fluid dynamics, or quantum-inspired optimization are encouraged to take part. Phase I concept proposals are open until 15 September 2026.

Sign up now to participate in the Global Quantum + AI Challenge and help turn quantum research into industrial outcomes.

EDITOR’S SPOTLIGHT.

➡️ Japan’s Institute for Molecular Science has begun operating Shunkai, the country’s first full-stack neutral-atom quantum computer, initially using about 50 qubits with plans to scale the system to roughly 500.

➡️ Shunkai integrates the hardware and software needed to turn user instructions into quantum operations, making it a research platform rather than only an experimental quantum processor.

➡️ Developed with Hitachi and U.S.-based Infleqtion through Japan’s Moonshot R&D Program, the system uses lasers to trap, arrange and control individual neutral atoms that serve as qubits.

➡️ Researchers plan to open parts of the platform to outside users working on applications and quantum error correction, potentially connecting hardware development with Japan’s software, research and industrial communities.

➡️ The project has set a target of 10,000 physical qubits with error-detection and correction capabilities by March 2031, although reaching that scale will require substantial improvements in control, reliability and system integration.

➡️ Shunkai exemplifies Japan’s broader quantum strategy, which combines targeted research, industry-academic collaboration, international partnerships, shared research hubs and support for commercialization.

Commentary:

Japan now has another tangible piece of its national quantum strategy in place.

The Institute for Molecular Science announced this week that Shunkai, Japan’s first full-stack neutral-atom quantum computer, is operational. The system will initially use about 50 qubits, with plans to increase that number to roughly 500 and eventually pursue a much more ambitious target of 10,000 physical qubits by March 2031.

As usual, the qubit numbers will probably receive most of the attention, but the more important part of the description should be “full stack.”

A quantum processor is only one part of a working computer. Users also need software that translates a problem into instructions, control systems that deliver those instructions to the hardware and measurement tools that turn the results into useful information. Shunkai brings these layers together in an operating system that researchers can actually use and improve.

Here’s a quick overview over how these machines work. The computer uses neutral atoms as qubits with lasers — known as optical tweezers — capture and arrange individual atoms. Additional laser or microwave signals control their quantum states. Researchers then read the results by observing light emitted by the atoms.

Neutral-atom systems have attracted interest partly because atoms are naturally identical, can hold quantum information for relatively long periods and may be rearranged during a computation. They also do not require the large dilution refrigerators used by superconducting quantum computers, although they still depend on sophisticated lasers, vacuum equipment and control systems.

As for background, Shunkai was developed under Japan’s Moonshot R&D Program by a team led by Professor Kenji Ohmori. The Institute for Molecular Science led the work, Hitachi contributed to the software stack and U.S.-based Infleqtion worked on the quantum-processing hardware.

That collection of highly regarded participants offers a compact illustration of Japan’s national approach.

Japan’s quantum strategy identifies technology development, international collaboration, industrialization, intellectual property and standards, and workforce development as five major pillars. It also calls for priority investment in areas such as gate-based quantum computers, quantum software, sensing, communications and artificial intelligence, supported by quantum innovation hubs connecting research and industry.

Shunkai touches several of those goals at once. It combines public research funding with university and corporate expertise. It brings a Japanese technology company into the software effort while drawing on an international hardware partner. Plans to give outside researchers access could also help develop applications, error-correction methods and people with experience using an actual neutral-atom system.

What’s worthy of spotlighting here is that, because national quantum plans can easily become lists of funding commitments, research goals and distant targets… and not much else. What we are seeing is aspirations that have turned into operations. These national plans are beginning to produce something that researchers and companies can use, in other words.

There are still reasons for caution. Moving from approximately 50 qubits to 10,000 is not a routine expansion. The project must maintain precise control over larger atomic arrays, improve the quality of quantum operations and demonstrate error detection and correction. Physical qubit count also says little by itself about the system’s ability to solve useful problems.

The project’s external-access plans may therefore be as important as its 2031 target. Allowing software researchers, theorists and companies to work with Shunkai could expose technical weaknesses, encourage new applications and create demand for supporting technologies.

Japan’s strategy is not simply to build one large quantum computer. It is to create the research, industrial and international connections needed to turn quantum technology into a working sector.

To make sure we don’t overhype this progress, Shunkai does not prove that Japan has completed that transition. But it does show that another part of the plan has moved from a policy document into an operating laboratory.

DATA SPOTLIGHT.

PacketLight Networks and NEC demonstrated quantum key distribution over a 400G dense wavelength division multiplexing (DWDM) network using a dual-fiber setup. They integrated NEC’s QKD system with PacketLight’s PL-4000M 600G Muxponder, achieving 100% data throughput and low latency, verified via a 100GbE tester. The QKD ran over a dedicated parallel fiber, maintaining quantum signal integrity. The result: a cost-effective, scalable quantum-safe model with zero performance tradeoffs on existing high-capacity infrastructure.
