Inductance and mutual inductance of superconductor integrated circuit features with sizes down to 120 nm. Part I
Sergey. K. Tolpygo, Evan B. Golden, Terence J. Weir +1
Data are presented on inductance of various features used in superconductor digital integrated circuits such as microstrip and stripline inductors with linewidths down to 120 nm an…
SFQ bias for SFQ digital circuits
Vasili K. Semenov, Evan B. Golden, Sergey K. Tolpygo
Superconductor electronics fabrication technology developed at MIT Lincoln Laboratory enables the development of VLSI digital circuits with millions of Josephson junctions per squa…
Very Large Scale Integration of Josephson-Junction-Based Superconductor Random Access Memories
Vasili K. Semenov, Yuri A. Polyakov, Sergey K. Tolpygo
Arrays of Vortex Transitional (VT) memory cells with functional density up to have been designed, fabricated, and successfully demonstrated. This progress is due to r…
Planarized Fabrication Process With Two Layers of SIS Josephson Junctions and Integration of SIS and SFS π-Junctions
Sergey K. Tolpygo, Vladimir Bolkhovsky, Ravi Rastogi +6
We present our new fabrication Process for Superconductor Electronics (PSE2) that integrates two (2) layers of Josephson junctions in a fully planarized multilayer process on 200-m…
Superconductor Digital Electronics: Scalability and Energy Efficiency Issues
Sergey K. Tolpygo
Superconductor digital electronics using Josephson junctions as ultrafast switches and magnetic-flux encoding of information was proposed over 30 years ago as a sub-terahertz clock…
Detection of a Schroedinger's Cat State in an rf-SQUID
Jonathan R. Friedman, Vijay Patel, W. Chen +2
We present experimental evidence for a coherent superposition of macroscopically distinct flux states in an rf-SQUID. When the external flux Phi_x applied to the SQUID is near 1/2…
