Building computers at the universe's energy limit

I am a Research Engineer at MIT's Center for Bits and Atoms working on superconducting digital electronics. My research focuses on adiabatic quantum-flux-parametron (AQFP) circuits, which operate near the thermodynamic limit of computation set by the relationship between entropy and information.

Prior to joining CBA, I spent 11 years as a Technical Staff Member at MIT Lincoln Laboratory, where I led programs developing memory and logic circuits using the SFQ5ee fabrication process. I have also worked with venture capital and nonprofit organizations on technology areas including long duration energy storage and power transmission at the grid scale.

Research

My work spans the full stack of superconducting computing system development, from low-level device physics to high-level architecture analysis. AQFP logic operates with energy dissipation near the Landauer limit (kT ln 2), making it a compelling candidate for future high-performance computing where energy efficiency is paramount. Current projects include developing design automation tools for AQFP circuits and demonstrating working processor architectures.
