2017 MRS Fall Meeting and Exhibit | Boston, Massachusetts

Tutorial EM08—Materials Science of Quantum Computing

Sunday, November 26, 2017
1:30 PM - 5:00 PM
Hynes, Level 2, Room 210

Quantum computing promises to revolutionize information technology as we know it today by changing the physical nature of the fundamental unit of information.  However, the physical limitations to creating a quantum computer originate in our ability to manipulate and control the basic materials that comprise quantum computing devices. This tutorial will provide an introduction to the relevant applied physics and the related material structures and compositions needed to create elementary quantum computing devices.
