Advancing electromechanical resonators towards terahertz frequencies opens vast bandwidths for phononic signal processing. In quantum phononics, mechanical resonators at these freq…
A kilometer photonic link connecting superconducting circuits in two dilution refrigerators
Yiyu Zhou, Yufeng Wu, Chunzhen Li +4
Superconducting quantum processors are a leading platform for implementing practical quantum computation algorithms. Although superconducting quantum processors with hundreds of qu…
High-efficiency, cryogenic-compatible grating couplers on an AlN-on-sapphire platform through bottom-side coupling
Yiyu Zhou, Mohan Shen, Chunzhen Li +2
Sapphire is a commonly used substrate for wide-bandgap III-nitride photonic materials. However, its relatively high refractive index results in low transmission efficiency in grati…
Unveiling the Pockels Coefficient of Ferroelectric Nitride ScAlN
Guangcanlan Yang, Haochen Wang, Sai Mu +7
Nitride ferroelectrics have recently emerged as promising alternatives to oxide ferroelectrics due to their compatibility with mainstream semiconductor processing. ScAlN, in partic…
