First Tunable, 'Noiseless' Amplifier May Boost Quantum Computing, Communications

Caption: In the JILA/NIST "noiseless" amplifier, a long line of superconducting magnetic sensors (beginning on the right in this photograph) 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 phase.
