The Quantum Genesis Files, Part Three
This article follows Part Two of The Quantum Genesis Files.
DOE has opened a new race toward fault-tolerant quantum computing. Many of the companies capable of running it have already spent years inside federal research, testing and validation programs.
The Department of Energy’s Quantum Genesis Q Competition has not yet told us who will compete for its planned $215 million.
Applications do not close until October 19.
But Washington does not need introductions to many of the companies developing the kinds of machines DOE wants.
IBM quantum computers have been used by researchers at Oak Ridge National Laboratory.
So have machines from Quantinuum, IonQ and Rigetti.
DARPA is separately scrutinizing proposed fault-tolerant systems from IBM, IonQ, Quantinuum, Atom Computing and QuEra.
Microsoft and PsiQuantum have advanced even further into a government verification program.
Several companies have participated in Department of Energy research centers or collaborated with DOE laboratories.
And some received major Commerce Department quantum awards only days before DOE announced Quantum Genesis.
This does not tell us who will apply.
It tells us something else.
The federal government has already spent years getting to know much of the field.
IBM
Start with perhaps the most familiar name.
IBM’s approach uses superconducting quantum processors, an architecture DARPA describes more specifically as modular superconducting processors.
IBM is currently in Stage B of DARPA’s Quantum Benchmarking Initiative, where the company must develop detailed research and development plans, identify technological risks and propose prototypes capable of reducing those risks.
That is hardly IBM’s first federal quantum relationship.
DOE’s Oak Ridge Leadership Computing Facility has provided researchers access to IBM machines through its Quantum Computing User Program.
The relationship dates back years.
DOE documented an Oak Ridge Quantum Computing Testbed Pathfinder project beginning in 2017 that partnered with IBM and IonQ while developing methods for evaluating quantum processors. The project carried funding of approximately $1.55 million per year for five years.
IBM also participated in multiple DOE National Quantum Information Science Research Centers established in 2020.
The relationship has therefore included research, hardware access, benchmarking and participation in DOE’s national quantum-center network.
Then there is manufacturing.
On September 16, the Department of Commerce finalized an award of up to $1 billion to Anderon, a newly created IBM subsidiary, for a quantum semiconductor foundry.
One day later, DOE announced Quantum Genesis.
None of this establishes that IBM will apply for Quantum Genesis.
It does establish that if IBM does appear at DOE’s starting line, the company will hardly be a stranger to the federal government.
Quantinuum
Quantinuum presents an even denser relationship map.
The company develops trapped-ion quantum computers using what DARPA describes as a quantum charge-coupled device architecture.
It is also in DARPA’s Stage B.
Oak Ridge currently purchases access to Quantinuum systems for scientists participating in its Quantum Computing User Program.
At ORNL’s 2026 Quantum Computing User Forum, Quantinuum joined IBM, IonQ and IQM in providing workshops and presentations directly to researchers.
The company’s federal connections extend beyond DOE.
On September 8, the Commerce Department finalized an award of up to $100 million to address manufacturing bottlenecks involved in scaling fault-tolerant trapped-ion computers.
The work includes integrated photonics, specialized semiconductor components and optical technologies.
Sandia National Laboratories also announced a collaboration with Quantinuum in August to evaluate quantum technologies, including the company’s Helios system.
Put together, the federal relationship covers access, evaluation, manufacturing research, laboratory collaboration and DARPA scrutiny of the company’s pathway toward a useful fault-tolerant computer.
That is a considerable amount of government familiarity with one architecture.
IonQ
IonQ gives us another trapped-ion runner, but one following its own technological path.
The company has longstanding connections to Oak Ridge.
DOE’s earlier Quantum Computing Testbed Pathfinder listed IonQ alongside IBM as a project partner.
IonQ was later added to Oak Ridge’s Quantum Computing User Program, and DOE researchers today can request access to IonQ hardware through the program.
IonQ has also reached Stage B of DARPA’s Quantum Benchmarking Initiative.
There is another connection through the broader DOE research-center ecosystem.
Christopher Monroe, one of IonQ’s founders, has served as a research lead within the DOE-funded Quantum Systems Accelerator.
That center is led by Lawrence Berkeley National Laboratory with Sandia National Laboratories as its lead partner. Its mission includes developing scalable quantum systems, benchmarks and error-corrected technologies.
The relationship is disclosed and consistent with the explicit purpose of DOE’s quantum centers, which were created to connect national laboratories, universities and private industry.
But it illustrates why mapping this ecosystem is more informative than simply listing government awards.
Money is only one kind of federal exposure.
Researchers, laboratories, hardware, intellectual property, benchmarking and scientific collaborations form another.
Microsoft and PsiQuantum
Microsoft and PsiQuantum occupy an unusual position because DARPA has already moved them beyond the stage reached by most of the companies in its current benchmarking initiative.
Both came through DARPA’s Underexplored Systems for Utility-Scale Quantum Computing program, the pilot effort later expanded into the Quantum Benchmarking Initiative.
In February 2025, DARPA selected Microsoft and PsiQuantum for its Validation and Co-Design stage.
That stage has the same technical objectives as Stage C of the larger initiative.
This is where government verification becomes particularly serious.
DARPA’s independent team evaluates whether the proposed system can actually be constructed as designed and operated as intended.
Microsoft is pursuing a topological approach to quantum computing.
It also has longstanding DOE relationships, including participation in the Oak Ridge-led Quantum Science Center and previous quantum research collaborations with national laboratories.
PsiQuantum is taking a dramatically different route.
Its architecture uses photons.
Commerce finalized an award of up to $100 million for PsiQuantum on September 8, targeting photonic materials, single-photon detectors and ultra-low-loss packaging.
PsiQuantum therefore sits in an interesting federal position.
DARPA is examining whether its architecture can become an industrially useful computer.
Commerce is helping address manufacturing problems associated with that architecture.
DOE is now offering performance incentives for fault-tolerant quantum computers.
Again, those are separate programs.
Together, they reveal how many different federal doors a single quantum technology can pass through.
Atom Computing and QuEra
The neutral-atom branch gives the government’s portfolio yet another architecture.
Atom Computing and QuEra are both in DARPA Stage B.
Instead of superconducting circuits or trapped ions, these companies use arrays of neutral atoms as qubits.
That distinction matters because nobody yet knows which architecture, if any, will ultimately prove easiest to scale into a useful fault-tolerant computer.
DARPA explicitly acknowledges the problem.
Unlike classical computing, quantum computing has no single dominant architecture.
Its Stage B cohort therefore spans neutral atoms, trapped ions, superconducting systems, silicon spin qubits and photonic technologies.
The government is not comparing slightly different versions of the same computer.
It is evaluating fundamentally different ways of building one.
Rigetti
Rigetti provides an example of how the federal roster changes as technology develops.
The company builds superconducting quantum computers.
Oak Ridge previously contracted for access to Rigetti processors through its Quantum Computing User Program. DOE researchers used Rigetti hardware alongside IBM systems for early benchmarking and scientific experiments.
Rigetti also entered Stage A of DARPA’s Quantum Benchmarking Initiative.
It does not appear on DARPA’s currently published Stage B list.
That distinction is worth preserving.
Federal participation is not a permanent stamp of technological approval. Programs change, contracts change, vendors advance at different speeds and government evaluators can reach different conclusions.
At the same time, Commerce has made a new investment.
Its quantum initiative identified up to $100 million for Rigetti to address scaling problems in superconducting systems, including readout electronics and next-generation cryogenic architectures.
The federal relationship therefore continues even as its form changes.
Google and the Rest of the Field
Google Quantum AI entered DARPA Stage A in September 2025 with its superconducting transmon architecture.
Google has also participated in the DOE-funded Quantum Systems Accelerator’s industry ecosystem alongside IBM and Microsoft.
But Google illustrates another reason this series should resist turning the federal quantum landscape into a simple leaderboard.
Different companies appear in different programs for different reasons.
DARPA is looking for credible paths toward utility-scale quantum computers.
DOE research centers pursue basic and applied science.
Oak Ridge purchases commercial access for scientific users.
Commerce is attacking manufacturing bottlenecks.
Quantum Genesis is establishing milestones for scientifically relevant fault-tolerant systems.
Participation in one does not guarantee participation in another.
Absence from one does not necessarily mean a company is technologically irrelevant.
Oak Ridge Has Been Taking Notes
Perhaps the most revealing institution in this entire network is not a company.
It is Oak Ridge National Laboratory.
Its Quantum Computing User Program began in 2017.
The program has purchased commercial quantum-computing subscriptions rather than forcing researchers to rely upon vendor demonstrations.
Scientists can run workloads on different architectures.
They can compare results.
They can study error behavior.
They can determine which machines are useful for which scientific problems.
In 2023, Oak Ridge researchers reported what the laboratory described as the first independent comparison of leading quantum computers.
They examined 24 processors and compared their results against performance figures promoted by vendors including IBM, Rigetti and Quantinuum.
That is important history for Quantum Genesis.
DOE is not suddenly confronting a collection of mysterious machines whose manufacturers must be taken at their word.
Parts of the Department have spent years learning how to test them.
Oak Ridge’s current program gives users access to IBM, IQM, IonQ and Quantinuum resources. The laboratory says it has purchased subscriptions to those vendor services and manages access for approved scientific projects.
Its annual user forums bring researchers and vendors together directly.
The 2026 forum included workshops from IBM, Quantinuum, IonQ and IQM.
DOE is therefore simultaneously a research sponsor, customer, scientific user and evaluator within portions of the commercial quantum market.
That arrangement is not hidden.
It is the program.
Nobody Has Won Yet
After mapping these relationships, one conclusion becomes difficult to avoid.
Washington has built a portfolio rather than placed a single bet.
Superconducting processors remain in the mix.
So do trapped ions.
Neutral atoms remain in the mix.
Photonics remains in the mix.
Silicon and other spin-based approaches remain under examination.
Microsoft is trying something considerably different with topological qubits.
Some companies have received direct federal awards.
Some provide hardware access to government scientists.
Some participate in federally funded research centers.
Some undergo DARPA verification.
Several occupy multiple categories simultaneously.
None of that establishes who will win DOE’s Quantum Genesis competition.
It does show that when applications arrive on October 19, federal evaluators may recognize quite a few names.
The government helped fund portions of the underlying science.
Its laboratories worked with commercial hardware.
Its researchers developed benchmarks.
DARPA began examining whether company roadmaps could survive technical scrutiny.
Commerce started financing manufacturing bottlenecks.
DOE is now constructing another validation system and offering financial rewards for demonstrated fault-tolerant performance.
The runners have been assembling for years.
So have the referees.

That leaves one final piece of the system to examine.
Who determines that a quantum computer has actually crossed the finish line?
Part Four of The Quantum Genesis Files will follow the benchmarks, laboratories and federal verification programs responsible for answering that deceptively difficult question.
