(16:52 + Q&A) Dr. Rabindra N. Das, MIT Lincoln Laboratory -- Presentation from 2023 Workshop on Quantum Computing: Devices, Cryogenic Electronics and Packaging (QC-DCEP) ...
Summary: Superconducting single-flux-quantum-based (SFQ) digital integrated circuits (ICs) are a promising candidate for a high speed and ultra-low energy dissipation computing system. Circuits based on several versions of SFQ-type logic, RQL (Reciprocal Quantum Logic), and AQFP( Adiabatic Quantum-Flux-Parametron) logic have been demonstrated with complexities reaching up to a few hundreds of thousands of gates. Packaging many superconducting ICs — and performing fast and nearly lossless operations between SFQ, RQL, AQFP, and CMOS -– is critical for a scalable computing architecture. In this talk, I will present a micro-bump based passive superconductive multi-chip module (SMCM) which distributes information between integrated circuits utilizing impedance controlled, lossless superconducting transmission lines.
