Head of Cryoelectronics

Christopher L. Ayala

Christopher Ayala is Head of Cryoelectronics at Atlantic Quantum, where he leads the company’s cryogenic electronics development and design.

Before joining Atlantic Quantum, Christopher was an Institute of Advanced Sciences (IAS) associate professor at Yokohama National University (YNU) in Japan. There he designed and demonstrated the world’s first adiabatic superconductor microprocessor, which was featured in media outlets such as IEEE Spectrum, Superconductor Week Magazine, Nikkei Cross Tech, and more.

During his PhD at Stony Brook University, he conducted research on superconductor electronics using single-flux-quantum (SFQ) logic. He also worked at NVIDIA where he investigated architectural power optimization techniques for next generation GPUs. From 2013-2015, he was a Post-Doctoral Fellow at IBM Research–Zurich where he worked on nanoelectromechanical (NEM) switches for energy-efficient computation, for which he received the 2014 ESSDERC Best Young Scientist Paper Award.

Christopher holds a PhD in Computer Engineering, and a combined MS/BEng in Electrical and Computer Engineering from Stony Brook University.
