Q-Factor emerged from stealth with $24 million in seed funding to develop a neutral-atom quantum computing architecture designed to scale beyond current system limits. The Tel Aviv–based startup said the round was led by NFXand TPY Capital, with participation from Intel Capital, Korea Investment Partners, Deep33, and the Matias family, along with a grant from the Israel Innovation Authority. Technion – Israel Institute of Technology and Weizmann Institute of Science are also shareholders, reflecting the company’s academic origins.
The company is focused on neutral atoms, a modality that encodes quantum information in individual atoms controlled with laser systems. Q-Factor positions scalability—not qubit fidelity alone—as the central constraint facing the industry. While neutral atoms offer advantages such as uniform qubits, long coherence times, and reduced wiring complexity, current systems remain limited to relatively small qubit counts. Q-Factor said it has identified architectural bottlenecks in existing approaches and developed a design intended to support continuous scaling from thousands to millions of qubits.
Q-Factor was founded by physicists Prof. Nir Davidson, Prof. Ofer Firstenberg, and Prof. Yoav Sagi, along with Dr. Guy Raz, combining research backgrounds in ultracold atoms, quantum optics, and Rydberg physics with experience in scaling deep-tech ventures. The company aims to translate decades of foundational research into a commercially viable platform capable of supporting large-scale quantum applications.

“The quantum computing industry needs a revolution, not an evolution,” said Prof. Ofer Firstenberg, co-founder and chief scientist of Q-Factor. “Current systems are too small to deliver on the promise of quantum computing, and incremental improvements alone aren’t going to close that gap. We’ve developed an architecture designed for continuous scalability, a Moore’s Law-like trajectory that can take neutral atom systems from thousands of qubits to millions and beyond.”
🌐 Analysis: Q-Factor enters a quantum computing market that is increasingly focused on scaling architectures rather than isolated performance gains. Neutral atoms have gained traction alongside superconducting and trapped-ion approaches, with multiple vendors and research programs exploring pathways to larger qubit arrays and fault-tolerant systems. The company’s emphasis on architectural redesign aligns with broader industry efforts to address system-level constraints such as control complexity, error correction, and manufacturability.
