Phys.org August 31, 2021 An international team of researcher (Russia, UK) theoretically considered wave mixing under the irradiation of a single qubit by two photon fields. The first signal was a classical monochromatic drive, while the second one was a nonclassical light. They addressed two examples of a nonclassical light: (i) a broadband squeezed light and (ii) a periodically excited quantum superposition of Fock states with 0 and 1 photons. The mixing of classical and nonclassical photon fields gives rise to side peaks due to the elastic multiphoton scattering. They showed that a side peaks structure is distinct from the […]
