Infleqtion
Overview
Full-stack quantum computing using neutral atom arrays with optical tweezer technology. Also develops quantum sensors and atomic clocks. Targets 30 logical qubits by 2026 and 1,000 by 2030.
Key Milestones
- 2007: Founded as ColdQuanta by Dana Anderson (University of Colorado)
- 2022: Rebranded to Infleqtion, expanded beyond cold atom technology
- 2023: Awarded $27.3M DARPA contract for quantum computing development
- 2024: Released Sqale quantum computer architecture
- 2025: Unveiled roadmap to 30 logical qubits by 2026, 1,000 by 2030
- 2025: JP Morgan collaboration — open-source QEC library reducing physical qubit needs by 10-100×
- 2026: Delivered UK's only operational 100-qubit system at National Quantum Computing Centre
Technology Approach
Infleqtion (formerly ColdQuanta) uses neutral atoms — individual rubidium or cesium atoms trapped in optical tweezers and arranged in customisable 2D/3D arrays. The Sqale architecture targets fault-tolerant quantum computing with a focus on logical qubits rather than physical qubit count.
Key differentiator: Infleqtion spans the full quantum technology stack — quantum computing, quantum sensing (atomic clocks, magnetometers), and quantum networking components. This diversification provides near-term revenue while the computing platform matures.
Recent Milestones
In March 2026, Infleqtion delivered the UK’s only operational 100-qubit quantum computing system at the National Quantum Computing Centre, supporting its roadmap toward 30+ logical qubits by end of 2026.
Competitive Position
Strengths: Broad patent portfolio (230+), diversified revenue streams (sensors + computing), DARPA backing, public company transparency.
Challenges: Neutral atom gate fidelities still catching up with trapped ions. Competing with well-funded QuEra and Pasqal in the same modality.
