Al epitaxial layers for quantum computers components

Getting ready for the quantum leap!

NAMBE 2015 Poster

One of the critical elements of quantum computer architectures are superconducting microwave resonators. Working in close collaboration with research groups at the Institute for Quantum Computing, we are developing more efficient components to bridge the gap between theory and actual implementation of these "super computers".  Very high quality resonators were recently developed, using patterned thin layers of aluminum (Al) on sapphire (A. Megrant et al, 2012). 

Our goal is to produce similar structures using more common and economically feasible substrates. High quality single crystalline and atomically smooth Al layers were grown on both gallium arsenide (GaAs) and silicon (Si). Some results were presented during the 2015 North American MBE conference.
