As MCQST Distinguished Lecturer, Christopher Monroe, Gilhuly Family Presidential Distinguished Professor of Electrical and Computer Engineering and Physics at Duke University is giving a series of talks targeted to varied audiences. This specialized seminar is designed for researchers working in the same field.

Quantum Networks with Atomic Memories

A large scale quantum computer will require optical interconnects, regardless of the qubit platform, thus allowing a modular architecture with full connectivity. Atomic systems are natural memory nodes for photonic interfaces, especially atomic ions, which already feature high-performance local quantum gates and near-perfect initialization and measurement. There are several atom/photon interface prototols for heralded remote entanglement using photonic qubits encoded in polarization, frequency, or time-bin. I will summarize recent advances in photonically-networked trapped ion systems. This includes progress on 3-node remote entanglement and the use of intervening SiV:diamond memory interfaces that will allow remote entanglement rates and fidelities to be as good as local entangement gates.

About Christopher Monroe

Christopher Monroe is the Gilhuly Family Presidential Distinguished Professor of Electrical and Computer Engineering and Physics at Duke University. He is also the Co-Founder and Chief Scientist of IonQ, Inc., the first public quantum computing company. Monroe has pioneered nearly all aspects of atom-based quantum computers and simulators, from demonstrations of the first quantum gate, monolithic semiconductor-chip ion trap, and photonic interconnects between physically separated qubits; to the design, fabrication, and use of full-stack ion trap quantum computer systems in both university and industrial settings. He is a key architect of the US National Quantum Initiative, a Fellow of the American Physical Society, Optical Society of America, the UK Institute of Physics, the American Association for the Advancement of Science, and is a member of the National Academy of Sciences.
