Helped establish trapped-ion quantum computing through laser cooling, a controlled quantum logic gate and deterministic entanglement, connecting precision measurement with experimental quantum information.
Physical Review LettersPhysical Review LettersNISTWineland is included for experiments that showed quantum information could be prepared, manipulated and shared in controlled atomic systems. The 1995 gate experiment demonstrated two quantum bits encoded in one trapped atom, while the 1998 work produced entanglement between two ions on demand. These are distinct steps toward scalable processing, not merely demonstrations of unusual quantum behavior. His work also connects computing to the precision-control techniques used in atomic clocks. The contributions are attributed to their experimental teams rather than to Wineland alone.

Work, in context- 1995
A controlled quantum logic gate
Wineland co-authored the NIST experiment with Christopher Monroe, D. M. Meekhof, B. E. King and W. M. Itano. It demonstrated a controlled-NOT gate using internal and motional states of one trapped atom as two quantum bits. The paper identifies decoherence effects and discusses extension to additional qubits.
Co-author with Christopher Monroe, D. M. Meekhof, B. E. King and W. M. Itano; the gate was a team experiment.

Entanglement produced on demand
Wineland and the NIST team reported deterministic preparation of entangled internal states of two trapped ions. Producing those states without selecting only favorable outcomes established a different capability from the earlier single-atom gate and addressed a requirement for larger quantum computations.
Co-author of the NIST experimental team’s paper; entanglement preparation was a team result.

Recognition for controlling individual quantum systems
Wineland shared the Nobel Prize in Physics with Serge Haroche for experimental methods that allow individual quantum systems to be measured and manipulated. NIST’s account connects the recognition to laser-cooled ions, quantum-computing operations and precision atomic clocks. The award recognizes experimental methods rather than a completed general-purpose quantum computer.
Co-recipient of the 2012 Nobel Prize in Physics with Serge Haroche.
