Rare-Earth Doped Oxides as Platforms for Scalable Quantum Memories

Presenter: Abhinav Prakash, Argonne National Laboratory and University of Chicago

Abstract: Quantum repeaters form the core of future quantum network and quantum key distribution for the transfer of quantum states over long distances. Implementation of quantum repeaters requires high performance quantum memories for the storage of these quantum states. Platforms for quantum memories also need to be versatile, so that they can be used for various other applications such as quantum sensing and quantum information processing. Quantum memories based on solid state devices provide such a platform and are advantageous due to their ease of device development and large-scale fabrication. In this talk, hear a brief overview of an optical quantum memory and discuss the fabrication methodologies that we being utilized towards the realization of scalable quantum memories.

Speaker Bio: Abhinav Prakash is a postdoctoral researcher at Argonne National Laboratory, and with the Pritzker School of Molecular Engineering, University of Chicago with Prof. Supratik Guha. Prakash's current research interests include synthesis of rare-earth doped oxides for applications in quantum information science. He received his PhD in materials science and engineering from the University of Minnesota, Twin Cities in 2019, under the supervision of Bharat Jalan. His doctoral research was focused on defect- engineering in perovskite oxide thin films grown using radical-based molecular beam epitaxy for room- temperature oxide electronics. Prakash is a recipient of the Impact Argonne Award and University of Minnesota Doctoral Dissertation Fellowship, among other honors.
