Jonathan King, Co-Founder & Chief Scientist, Atom Computing
Jonathan King has built his career around one of the central challenges in quantum computing: how to turn the unusual behavior of individual atoms into a controllable, scalable computing platform.
As Co-Founder and Chief Scientist of Atom Computing, Jonathan King has helped shape the company’s neutral-atom approach from its founding in 2018. He also leads its applications team, which focuses on benchmarking and developing use cases for the company’s systems.
Atom Computing uses neutral atoms as qubits, trapping and manipulating them with lasers rather than fabricating each qubit into a conventional chip. The architecture offers several potential advantages, including large qubit arrays, long coherence times and flexible connectivity.
Jonathan King’s work sits at the intersection of fundamental physics, hardware design and the practical question that now defines much of the industry: which quantum architectures can ultimately deliver useful, error-corrected computation.
The Distinction
King’s significance lies in helping advance a hardware approach that has moved rapidly from a specialist research field into one of the most closely watched areas of quantum computing.
Neutral atoms provide a fundamentally different path from superconducting circuits, trapped ions and topological architectures. Because atoms of the same element are naturally identical, they offer an attractive foundation for building large, uniform arrays of qubits.
Atom Computing has pushed that approach to increasingly large systems.
Its current architecture includes more than 1,200 physical qubits, while work with Microsoft has demonstrated 24 entangled logical qubits and computation using 28 logical qubits, important steps toward systems where error correction, rather than physical qubit count alone, becomes the central measure of progress.
King has helped shape that technical direction from the beginning.
The Bigger Signal
His work reflects a broader truth about the quantum race: the dominant hardware architecture has not yet been decided.
Different companies are pursuing fundamentally different physical systems, each with its own strengths and constraints. The competition is increasingly shifting away from headline physical-qubit counts toward a harder question, which architectures can produce reliable logical qubits, support effective error correction and scale without becoming prohibitively difficult to control.
Neutral atoms are now firmly part of that competition.
The next step is becoming particularly relevant to Denmark. Microsoft and Atom Computing are co-developing Magne, a resilient quantum computer that will be operated by QuNorth in Copenhagen. The system is expected to combine Atom Computing’s 1,200-plus physical qubits with Microsoft’s quantum software stack, with deployment targeted for early 2027.
That is why The Hardware Visionary fits.
Jonathan King is helping advance one of the industry’s most ambitious hardware bets — while increasingly connecting that hardware to the applications, logical-qubit performance and real-world systems that will ultimately determine its value.
What to Watch: Whether neutral-atom systems can translate their advantages in scale, uniformity and reconfigurability into sustained logical performance — and whether projects such as Magne can move that architecture closer to useful, error-corrected quantum computing.
