This paper presents a sub-4-dB NF 50–70.9 GHz LNA with a defectly coupled transformer. The source-to-gate coupled feedback in the input transformer network is inhibited for wideband simultaneous noise...
Superconducting microwave-frequency circuits afford a powerful laboratory for testing the fundamental tenets of quantum mechanics while advancing the frontier of computing and sensing hardware that ha...
In this presentation, I will give a general overview of trapped-ion quantum computing, focusing specifically on the needs for control electronics. We will discuss noise mechanisms present in operation...
The ion trapped in a profiled electric potential has been considered as a good candidate for the qubit in quantum computing. While the trapped ions offer advantages of a long coherence time and high-f...
The talk will outline the different platforms to build controllable quantum dots and their characteristics. The confinement, single and multi electron state and exchange interaction will be explained....
The successful large-scale integration of quantum circuits hinges on a thorough understanding of their fundamental building blocks. To bridge the gap between academic proof-of-concept demonstrations a...
Silicon-Germanium (SiGe) heterojunction bipolar transistors (HBTs) have shown high current gain and high cut-off frequencies at cryogenic temperatures. These features can be traded for low noise and l...
In this talk, recent (and on-going) advances in backscattered transmitters and wake-up receivers with consumption down to the sub-µW peak power range are presented. The underlying concepts are support...
The lack of compact models in commercial PDKs that have been validated at Cryogenic Temperature (CT) makes the design of cryo-CMOS circuits a real challenge. The designs can unfortunately not be verif...
Applications in radio astronomy and quantum computing require microwave cryogenic low-noise amplifiers with as low of noise as possible. Characterization of these devices requires special approaches, ...
