As part of the Q-NEXT quantum research center, Randall Goldsmith of the University of Wisconsin-Madison studies the interplay of light and matter, harnessing it for quantum information technologies.

Advancements in AFSNSPD fabrication are discussed, emphasizing techniques that improve detector performance for applications in quantum computing and sensing.

This study published in the IEEE Journal of Selected Topics in Quantum Electronics offers a detailed guide for fabricating fractal SNSPDs, while addressing key challenges in the fabrication process.

The fabrication process begins with creating the optical microcavity by coating a silicon wafer with six or eight alternating layers of silicon dioxide (SiO 2) and tantalum oxide (Ta 2 O 5) using ...

One notable type is the superconducting nanowire single-photon detector (SNSPD). SNSPDs utilize ultra-thin superconducting wires that quickly transition from a superconducting state to a resistive ...

Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very ...
