-          that can be controlled on sub-nanosecond timescales. Recent research examines strong light-matter interactions in the circuit quantum 
-          electrodynamics architecture, with a goal of generating long-range many body entanglement. Silicon and diamond are ideal host materials 
-          for spin coherence, leading to spin coherence times that now approach 10 seconds. A major effort in the group consists of developing a
