Today’s Brief Commentary:
Today’s newsletter is a smorgasbord of news and article types, including financial moves, applications, a deep dive on neutral atoms, an analyst’s thoughts on quantum computing roadmaps, and a bottom-up view on defining quantum advantage. The individual links also have a new feature, which is a list of companies mentioned in the press release, news, or article.
In the Spotlight is a press release about 23 commercial, academic, and government partners in the European Union banding together “for the industrialisation of superconducting quantum chip technologies over the next six years.”
I’m a little surprised that they are not including silicon spin semiconductor technology as well, but perhaps they feel the tech is not mature enough, has too many different manufacturing concerns, or enlarges the group of competitors too much. Then again, maybe none of the spin companies wanted to participate.
In any case, this is an example of regional quantum sovereignty versus national quantum sovereignty. In the latter, the primary goal should be to build a quantum computing system that provides Practical Quantum Advantage (PQA) and Cryptographic Relevance for national security. Also important are domestic jobs and economic growth. A country must maintain its freedom of action to the maximum amount possible.
For the regional version, we can consider shared manufacturing facilities, as is the case here; a complete and secure supply chain; freedom of movement for a trained and educated workforce; regional economic growth; and insulation from geopolitical economic and military threats.
There are countries within the EU that want both national and regional quantum sovereignty, as is their right.
As I have stated many times before, country-specific quantum policies often fall short of the goal of having a sufficiently large and performant quantum computing system to meet their domestic needs. I was surprised several weeks ago to hear a national government representative speak of having such a system “based” in their nation when I fully expected a statement about its being built and deployed there. Maybe this was a slip of the tongue or a politically wrangled sentence, but it was a letdown.
Not every company can or should build a PQA quantum computing system within its borders. Many may be essential for necessary supply chain components or workforce. The key questions to be considered in order are:
- Should we better support in-country QPU and software companies grow to scale and maturity faster?
- Can we confidently get the same within our economic region or from a strong ally?
- Are there more international partners who can provide what we need more quickly and effectively, perhaps even before we develop domestic or regional capabilities?
Speaking of countries, regions, QPUs, and software, next up is a message from our sponsor …

IBM Offers a Prescription for Identifying Quantum Advantage
https://www.hpcwire.com/2025/07/07/ibm-offers-a-prescription-for-identifying-quantum-advantage/
Author: John Russell
Date: Monday, July 7, 2025
Companies Mentioned: IBM
Commentary: Quantum Advantage is personal: can quantum plus classical systems working together perform significantly better to solve MY problems? As much as it may be of intellectual interest, I care much less about what they can do for other people. I especially care much less about solving useless problems that might take a classical systems a megapetagigamillitriceratopillion years.
Excerpt: No doubt there will be a flurry QA claims in the coming years. Being able to quickly and accurately assess them should help quantum computing make the transition to becoming a practical tool easier and increase user confidence. Having a checklist of QA attributes to review can’t hurt, but one expects bottom line performance versus a classical system to quickly become the real arbiter.
Atomic explosion: After faltering early on, quantum computers fashioned out of individual atoms retake the lead
https://www.science.org/content/article/quantum-computers-made-individual-atoms-leap-fore
Author: Adrian Cho
Date: Thursday, July 10, 2025
Companies Mentioned: Atom Computing, Infleqtion, Pasqal, planqc, QuEra Computing
Commentary: Excellent survey article on neutral atom quantum computing.
Excerpt: But, thanks to a few key advances, atom-based quantum computing has come roaring back. Physicists can now assemble arrays of thousands of atoms—thousands of potential qubits. Because all the atoms of a particular element and isotope are identical, they should be more reliable and easier to control than manufactured superconducting qubits.
Quantum Computing Applications
Simulating Fluid Mechanics using Quantum Computing on Amazon Braket with Haiqu and Quanscient
Authors: Dmitri Iouchtchenko; Michael Brett; Ljubomir Budinski; Maciej Koch-Janusz; Mykola Maksymenko; Ossi Niemimäki; Valtteri Lahtinen; Vidyasagar Ananthan; and Vladyslav Bohun
Date: Tuesday, July 15, 2025
Companies Mentioned: Amazon Web Services, Haiqu, Quanscient Oy
Excerpt: Numerical simulations of complex fluid dynamics, electromagnetics and thermomechanical problems are crucial in the automotive and aerospace industries for designing and optimizing components like airplane wings, yet modeling continuum physics on high-resolution grids pushes classical computing to its limits. Quantum computing offers a potential path to overcome these barriers by encoding large simulation grids with fewer computational resources and potentially accelerating numerical solvers.
However, since these quantum applications require the execution of deep circuits beyond the coherence times available on today’s hardware, they are often considered impractical in the immediate future. As finalists in the Airbus and BMW Quantum Mobility Challenge in 2024, a joint team from Haiqu and Quanscient showed that solving these difficult problems may be possible sooner than expected. Today, we explore in more detail how the team approached the challenge.

Photonic quantum information with time-bins: Principles and applications
https://arxiv.org/abs/2507.08102
Authors: Singh, Ashutosh; Sethia, Anuj; Esmaeilifar, Leili; Valivarthi, Raju; Sinclair, Neil; Spiropulu, Maria; and Oblak, Daniel
Date: Thursday, July 10, 2025
Excerpt: Long-range quantum communication, distributed quantum computing, and sensing applications require robust and reliable ways to encode transmitted quantum information. In this context, time-bin encoding has emerged as a promising candidate due to its resilience to mechanical and thermal perturbations, depolarization from refractive index changes, and birefringence in fiber optic media. Time-bin quantum bits (qubits) can be produced in various ways, and each implementation calls for different considerations regarding design parameters, component compatibility (optical, electrical, electro-optical), and measurement procedures. Here, we provide a comprehensive overview of experimental methods for preparing and characterizing time-bin qubits (TBQs) for quantum communication protocols, with an assessment of their advantages and limitations. We discuss challenges in transmitting TBQs over optical fibers and free-space channels, and methods to overcome them. We also analyze the selection of key time-bin parameters and component requirements across experiments. This leads us to explore the preparation and characterization of time-bin entanglement and examine requirements for interference of time-bins from separate sources. Further, we cover preparation and characterization techniques for high-dimensional time-bin states, namely qudits, and the generation of time-bin entangled qudit pairs. We review time-energy entanglement and key experimental realizations. Finally, we present notable applications of time-bin encoded quantum states, from quantum communication protocols to photonic quantum computation. This work serves as an accessible introduction and a comprehensive review of recent developments.
Roadmaps
Here is What’s Missing from All Those Quantum Roadmaps
https://quantumcomputingreport.com/here-is-whats-missing-from-all-those-quantum-roadmaps/
Author: Doug Finke
Date: Saturday, July 12, 2025
Companies Mentioned: Alice & Bob, IBM, IQM Quantum Computers Oy, Microsoft, Oxford Ionics, Oxford Quantum Circuits, Pasqal
Excerpt: So all quantum providers should look at their technology portfolios and make sure they have in place all elements of a full quantum stack. Although a few end users might be able to create something meaningful without the missing pieces, most will not. And it would be great for the providers to show more on how they will be supporting the full stack in future releases of their quantum roadmaps.
