Robert J. Schoelkopf (born January 24, 1964 in New York City ) is an American experimental solid-state physicist who develops nanodevices for quantum information theory ( quantum computers ).

Life

Schoelkopf is the son of an art dealer. He graduated from Princeton University with a bachelor's degree cum laude in 1986 and received his PhD from Caltech in 1995 . 1986-1988 he was an engineer (low temperature physics, electronics) in the Goddard Space Flight Center , NASA , where he developed instruments for space missions. From 1995 he was a lecturer and from 1998 assistant professor at Yale University . In 2003 he became Professor of Applied Physics, where Sterling Professor of Applied Physics is. He was director of the Yale Center for Microelectronic Materials and Structures and is director of the Yale Quantum Institute.

He developed nanoelectronic devices based on quantum effects, for example the Radio Frequency Single Electron Transistor (RF-SET) in 1998 . It can measure quantum transport on the one-electron level on the nanosecond time scale. He and his group are further developing their electrometers and quantum amplifiers and working on ultra-sensitive detectors for sub-millimeter radiation that can count individual photons. He also investigates superconducting quantum dots , the dynamics of which are determined by individual Cooper pairs . They have potential applications in quantum computers and enable the study of decoherence.

He also worked with the theorist Steven M. Girvin on the development of circuit technology for future quantum computers . In 2007, he and Michel Devoret coupled two superconducting qubits via a quantum bus . In 2009 he and Girvin and others demonstrated the execution of 2-qubit algorithms with a superconducting quantum processor. In 2004 he and Girvin were the first to demonstrate Cooper boxes or artificial atoms made of Cooper pairs and their strong coupling to photons, which was pioneering work in the field of circuit quantum electrodynamics (circuit QED). Cooper pairs are isolated on a superconducting "island" that is connected to a superconductor reservoir of Cooper pairs via Josephson junctions. Their potential energy can be controlled externally by changing the applied voltage (as can the number of Cooper pairs). Pairs via the voltage at the Josephson junctions).

He is a Fellow of the National Academy of Sciences (2015), the American Academy of Arts and Sciences (2016) and the American Association for the Advancement of Science and the American Physical Society .

Awards

In 2014 he received the Fritz London Memorial Prize with Michel Devoret and John Martinis and the John Stewart Bell Prize with Devoret in 2013. In 2014 he was one of the recipients of the Max Planck Research Award, he received the NASA Technical Innovator Award and he received the Joseph F. Keithley Award for metrology from the American Physical Society in 2009.
