Abstract:
1. A superconducting Analog-to-Digital Converter (ADC), comprising: a sequence of stages, wherein said stages comprise resonators, wherein each one of said resonators uniquely pertains to one of said stages, wherein said stages number N, with N being at least 2, wherein said stages and said resonators are being characterized by an order in said sequence, said order having values from 1 through N, and wherein an analog signal to be digitized is being received by a stage having N as said order; active superconducting components, wherein said active superconducting components directionally couple pairs of said resonators, wherein said orders of said resonators in said pairs are adjacent to one another, wherein each of said pairs is having a higher order resonator and a lower order resonator, wherein said active superconducting components electrically shield said higher order resonator from said lower order resonator; and wherein said ADC is characterized as being an N
