Scalable microwave-to-optical transducers at single photon level with spins

Posted by klaurent Caltech

Kavli Affiliate: Andrei Faroan | Summary:Microwave-to-optical transduction of single photons will play an essential role in interconnecting future superconducting quantum devices, with applications in distributed quantum computing and secure communications. Various transducers that couple microwave and optical modes via an optical drive have been developed, utilizing nonlinear phenomena such as the Pockels effect and a […]

Design of an 8-Channel 40 GS/s 20 mW/Ch Waveform Sampling ASIC in 65 nm CMOS

Posted by klaurent Chicago

Kavli Affiliate: Eric Oberla | Summary:1 ps timing resolution is the entry point to signature based searches relying on secondary/tertiary vertices and particle identification. We describe a preliminary design for PSEC5, an 8-channel 40 GS/s waveform-sampling ASIC in the TSMC 65 nm process targetting 1 ps resolution at 20 mW power per channel. Each channel […]

AuNR-SMA: Automated Gold Nanorod Spectral Morphology Analysis Pipeline

Posted by klaurent Berkeley

Kavli Affiliate: Paul Alivisatos | Summary:The development of a colloidal synthesis procedure to produce nanomaterials of a specific size with high shape and size purity is often a time consuming, iterative process. This is often due to the time, resource and expertise intensive characterization methods required for quantitative determination of nanomaterial size and shape. Absorption […]

The white-light superflares from cool stars in GWAC triggers

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Guang-Wei Li, Liang Wang, Hai-Long Yuan, Li-Ping Xin, Jing Wang | Summary: M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the […]
