Atom Computing, Microsoft and the Magne Logical Qubit Machine
A partnership of atoms and software
Atom Computing builds neutral atom computers. Microsoft brings software that it calls qubit virtualization, which handles the encoding and error handling that turn many noisy physical qubits into fewer, better logical ones. Together they have produced some of the most talked about logical qubit results, and they are building a machine that people can actually order. For the basics of the hardware, see neutral atom computers explained.
The November 2024 result
In a Microsoft blog post dated November 19, 2024, the teams reported creating and entangling 24 logical qubits in a GHZ state, which they described as the most entangled logical qubits on record. They also reported running computations on 28 logical qubits built from 112 physical qubits, using a Bernstein-Vazirani test, with better accuracy than the same job on bare physical qubits. Error numbers, as reported:
- With errors and atom losses detected but not corrected, the logical error rate was 10.2 percent, about 4.1 times better than a 42 percent physical baseline.
- With errors detected and losses both detected and corrected, the logical error rate was 26.6 percent, about 1.6 times better than the physical baseline.
These are modest absolute numbers. An error rate of 10 percent is far from what a useful algorithm needs, and the result is best read as a proof that the pieces work together on real hardware. Some researchers also pushed back on the "record" wording, since definitions of an entangled logical state differ between labs. That honest debate is part of how the field improves.
Magne: the planned Level 2 machine
Microsoft frames progress in three levels: Level 1 is noisy physical qubits, Level 2 is machines built on logical qubits with error correction, and Level 3 is full fault tolerance. In July 2025 reports said that EIFO, Denmark's export and investment fund, and the Novo Nordisk Foundation would invest 80 million euros (roughly 40 million each) to set up QuNorth and buy Magne. Reported specs: 50 logical qubits built from 1,225 physical neutral atoms, hardware from Atom Computing and software and cloud integration from Microsoft. It would be 100 percent Danish owned, with priority access for Nordic users.
Timing is reported inconsistently: one report said ready for use by the end of 2026, another said operational in early 2027. As of October 9, 2026, treat it as a target that has not been announced as delivered. We did not find a source confirming completion.
Strengths, weaknesses, and what to look for
Strengths: neutral atoms scale to large arrays and the Microsoft stack gives users a path from experiments to cloud access. Weaknesses: the published error rates so far are high, atom loss is a challenge, and 50 logical qubits will only be useful if their error rates are low enough to run meaningful circuits. A fair test will be published benchmarks on Magne after delivery.
The bigger picture
A national investment in a machine whose headline unit is the logical qubit, not the physical qubit, signals a shift in how the industry talks about progress. Compare with Helios and the QuEra and Harvard work to see how three different groups are racing toward the same goal. Microsoft also pursues a separate topological bet, see topological qubits.

Questions to ask next
Once Magne is delivered, the useful questions are simple. What are the logical error rates on real circuits? How long can it run before atom loss interferes? Who gets access, and on what terms? Are results published so others can check them? Clear answers will turn a promising partnership into a proven platform, and that is a milestone worth cheering for.

Frequently asked questions
What is a Level 2 quantum computer?
In Microsoft's framing, a machine built on logical qubits with error correction, between noisy Level 1 machines and fully fault tolerant Level 3.
Is Magne running yet?
Not confirmed as of October 9, 2026. Reports gave end of 2026 or early 2027 as the target.
Were the 2024 error rates good?
They were better than the physical baseline but still high, for example 10.2 percent logical error with detection only. It was a proof of concept.
Is QNT related to these companies?
No. The memecoin is independent and unaffiliated.
