Develops neutral-atom quantum processors, with research spanning multi-qubit entanglement, quantum algorithms and measurements that preserve the information stored in neighboring atomic qubits.
NSF Public Access Repository / NaturePhysical Review XSaffman connects the physics of individually controlled atoms to the operations a programmable quantum computer needs. His publications address both entangling several qubits and measuring selected atoms while protecting other qubits. These are distinct engineering steps: preparing useful quantum states does not by itself provide the repeated measurements required for error correction. His inclusion reflects documented experimental contributions to that progression and an active neutral-atom research program at Wisconsin.

Multi-qubit operations on a neutral-atom computer
Saffman co-authored an experimental report on multi-qubit entanglement and algorithms using a neutral-atom quantum computer. The publication documents a move from individual atomic control toward coordinated operations on a programmable quantum processor.
Co-author of the collaborative 2022 neutral-atom experiment.

Measuring ancillas while protecting data qubits
His team demonstrated midcircuit measurement in a single-species neutral-atom processor. Data qubits were temporarily stored in protected internal states while ancillas were measured, with dynamical decoupling helping preserve coherence before computation resumed.
Co-author of the collaborative midcircuit-measurement experiment.

Keep in perspective
The measurement result is a component needed for error correction; it is not presented as a complete fault-tolerant computer.
