Robert J. Schoelkopf III (born January 24, 1964) is an American physicist, most noted for his work on quantum computing as one of the inventors of superconducting qubits.

[2] Schoelkopf's main research areas are quantum transport, single-electron devices, and charge dynamics in nanostructures.

Robert Schoelkopf focuses his research on the development of superconducting devices for quantum information processing, which might eventually lead to revolutionary advances in computing.

Schoelkopf's techniques emphasize high-speed, high-sensitivity measurements performed on nanostructures at low temperatures.

Together with his former supervisor Daniel Prober and his laboratory team, Schoelkopf invented the Radio-Frequency Single-Electron Transistor, an electrometer capable of measuring sub-electron charges on nano-second timescales.

Schoelkopf's current research focus, together with Michel Devoret and Steven Girvin of the Yale Department of Applied Physics, is to further develop superconducting circuits that might one day lead to a practical quantum computer.

Other projects are directed at developing "hybrid" quantum systems based on integrating cold atoms, molecules, or electrons with solid-state circuits.
