Broadband Ultra Low-Noise Superconductor/Semiconductor Interfaces for Quantum Systems

Tuesday, September 30, 2014

Prof. Joseph Bardin

Host: Prof. James Buckwalter

In a number of critical scientific fields, the highest performance instrumentation exploits superconducting electronics to achieve unprecedented performance. For example, the microwave approach to quantum computing requires making return loss measurements at X-band with as few as five photons in the reflected signal. This in turn requires amplifiers with noise performance approaching the vacuum fluctuation limit, TQ = hf/2k ≈ 0.2 K. Such noise performance can only be achieved using superconducting parametric amplifiers—all demonstrated semiconductor devices have exhibited fundamental performance limits at least one order of magnitude above this limit, even when cooled to cryogenic temperatures. Recent progress in superconducting devices has created a growing interest in implementing highly scaled systems with applications including free space optical communications, radio astronomy, and quantum computing. Such systems will require high-performance semiconductor interface circuitry [More...]
