2016 MRS Fall Meeting

Tutorial EM1.2 - Materials Science of Quantum Computing, Part 2

Nov 27, 2016 8:30am ‐ Nov 27, 2016 12:00pm


Quantum computing promises to revolutionize information technology as we know it 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. The tutorial provides an introduction to the relevant applied physics and the related material structures needed to create elementary quantum computing devices.
Part two of the tutorial will explore connections to actual material structures, their design, selection criteria, and means of fabrication for existing quantum information devices including:

- Ion trap qubits
- Silicon germanium donor qubits
- Silicon germanium quantum dot qubits
- Superconducting quantum circuit qubits

For each technology, relationships between decoherence measurements, interactions of the quantum state with materials and defects, and current understanding of the microscopic origins of materials defects will be presented.
