On-chip quantum technologies based on rare-earth ion crystals
Thursday, October 18, 2018 - 4:30pm to 5:30pm
Venue: 
Huang 018
Speaker: 
Dr. John Bartholomew - Postdoctoral Researcher Fellow - California Institute of Technology
Abstract / Description: 

Quantum technologies for computing, communication, and metrology become much more powerful if they are part of an integrated network operating at the quantum level. The first part of the this talk will introduce some of the interconnect technologies that can help to build up large quantum networks, including quantum memories and transducers. The second part of the talk will focus on demonstrations of these types of interconnects in crystals containing rare-earth ions, including on-chip technology developed at Caltech.

Bio: 

John Bartholomew is a postdoctoral research fellow at the California Institute of Technology working in the Nanoscale and Quantum Optics Group lead by Professor Andrei Faraon. His research focuses on using rare-earth ions in crystals to create devices that connect the microwave and optical domains at the quantum level. 

He completed his PhD studying integrated rare-earth ion quantum hardware at the Australian National University in 2014 and then worked as a postdoctoral researcher at Chimie ParisTech (France) investigating nanocrystal systems. He then joined the Faraon Group at Caltech as the American Australian Association Northrop Grumman Fellow in 2016.
