Superconducting Parametric Amplifier

HYPRES, in collaboration with University of California, Berkeley, proposes to transition superconducting parametric amplifier technology into a robust line of products. In Phase I, we designed a compact package for lumped-element Josephson parametric amplifiers (LJPA) fabricated by our collaborators at MIT Lincoln Laboratory. We have also established the feasibility of digitization of the amplified output of qubits with a superconductor analog-to-digital converter (ADC) chip. This was accomplished by leveraging the complete digital data acquisition and processing infrastructure from HYPRES cryocooled digital-RF receiver product. In Phase II, we will develop a parametric amplifier product that will accommodate existing chips as well as improved LJPA chips which we plan to fabricate. Additionally, the analog output of the amplifier will be converted to the digital domain using a sensitive analog-to-digital converter to enable multiplexed operation.
