Title: Engineering quantum technologies with spins in semiconductors

Speaker: David Awschalom

Abstract: Individual defects in diamond, silicon carbide, and other wide-gap semiconductors have attracted interest as they possess an electronic spin state that can be employed as a solid-state quantum bit from cryogenic to ambient temperatures.  These systems have a built-in optical interface in the visible and telecom bands, retain their coherence over millisecond timescales, and can be polarized, manipulated, and read out using a simple combination of light and microwaves.  We discuss recent single qubit quantum control measurements in silicon carbide including gigahertz manipulation, single nuclear spin quantum memories, entangled quantum registers, and advances in extending the quantum coherence in both commercial and custom CVD-grown electronic materials.
