Title: Physics, amplifier, noiseless
Description: In the JILA/NIST 'noiseless' amplifier a long line of superconducting magnetic sensors (beginning on the right in this colorized micrograph) made of sandwiches of two layers of superconducting niobium with aluminum oxide in between, creates a 'metamaterial' that selectively amplifies microwaves based on their amplitude rather than frequency or phase.
