Ultra-low loss quantum photonic circuits with single quantum emitters

Recent collaborative work between NIST (led by alumnus Marcelo Davanco), UCSB, MIT, and KIST has resulted in the demonstration of ultra-low loss quantum photonic circuits integrated with single quantum emitters. 

This work is the first to combine ultra-low loss photonic circuits (1 dB/m) that are the backbone of integrating increasingly large numbers of photonic components with single quantum emitters, in this case based on single epitaxial quantum dots. The quantum dots give access to high-brightness, triggered single-photon generation, amongst other features. 

This work was highlighted by Nature Communications in its 'Top 25 Physics Articles of 2022' and by NIST, UCSB, and phys.org.
