Dr. Saffman’s Achievements in Neutral-Atom Quantum Technologies
Dr. Mark Saffman has received the 2026 Norman F. Ramsey Prize from the American Physical Society for his pioneering work in neutral-atom quantum technologies. The award recognizes his “seminal developments” in quantum information processing using neutral atoms, enabling the investigation of complex problems beyond the reach of classical computers. This achievement underscores the validation of Infleqtion’s approach, which focuses on building scalable and reliable quantum systems based on neutral atoms, bridging academic research with engineered solutions.
Dr. Saffman’s foundational work includes the development of the first CNOT gate for atomic qubits and advancements in Rydberg-mediated entanglement. These innovations were crucial in establishing neutral-atom systems as a leading platform for scalable, fault-tolerant quantum computers. He initially developed these techniques as a Professor at the University of Wisconsin–Madison, focusing on quantum control of neutral atoms and high-fidelity two-qubit operations using Rydberg blockade.
Currently Chief Scientist at Infleqtion, Dr. Saffman is focused on transitioning laboratory innovations into engineered systems. He co-authored the first demonstration of a quantum algorithm executed on an atomic quantum computer, and his work remains instrumental to Infleqtion’s entire portfolio of scalable, fault-tolerant quantum solutions—including quantum computers, sensors, and software for various applications.
Infleqtion’s Leadership in Neutral-Atom Quantum Technology & Products
Infleqtion is establishing itself as a global leader in neutral-atom quantum technology, designing and building both quantum computers and precision sensors. The company’s portfolio extends to quantum RF systems, quantum clocks, and inertial navigation solutions, serving governments, enterprises, and research institutions. Infleqtion’s planned merger with Churchill Capital Corp X (NASDAQ: CCCX), announced in September 2025, signals further growth and investment in this rapidly developing field.
