Prototype ‘optics table on a chip’ places microwave photon in two colors at once

(PhysOrg.com) — Researchers at the National Institute of Standards and Technology (NIST) have created a tunable superconducting circuit on a chip that can place a single microwave photon (particle of light) in two frequencies, or colors, at the same time.
