A tunable high-Q millimeter wave cavity for hybrid circuit and cavity QED experiments

Aziza Suleymanzade, Alexander Anferov, Mark Stone +4 more

The millimeter wave (mm-wave) frequency band provides exciting prospects for quantum science and devices since many high-fidelity quantum emitters, including Rydberg atoms, molecules, and silicon vacancies, exhibit resonances near 100 GHz. High-Q resonators at these frequencies would give access to strong interactions between emitters and single photons, leading to rich and unexplored quantum phenomena at temperatures above 1 K. We report a 3D mm-wave cavity with a measured single-photon internal quality factor of 3×107 and mode volume of 0.14×λ3 at 98.2 GHz, sufficient to reach strong coupling in a Rydberg cavity quantum electrodynamics system. An in situ piezotunability of 18 MHz facilitates coupling to specific atomic transitions. Our unique, seamless, and optically accessible resonator design is enabled by the realization that intersections of 3D waveguides support tightly confined bound states below the waveguide cutoff frequency. Harnessing the features of our cavity design, we realize a hybrid mm-wave and optical cavity, designed for interconversion and entanglement of mm-wave and optical photons using Rydberg atoms.The millimeter wave (mm-wave) frequency band provides exciting prospects for quantum science and devices since many high-fidelity quantum emitters, including Rydberg atoms, molecules, and silicon vacancies, exhibit resonances near 100 GHz.

Interplay of phase-sensitive amplification and cascaded four-wave mixing in dispersion-controlled waveguides

Aude Martin, Sylvain Combrié, A. Willinger +2 more

Phase-sensitive parametric interactions can selectively process the two complex quadratures of the optical field. We implement phase-sensitive amplification in a large band-gap semiconductor photonic crystal waveguide in order to avoid two-photon absorption and free-carrier-related effects. Experimentally, an extinction ratio of 15 dB is achieved in a 1.5-mm-long photonic crystal waveguide, at a peak pump power of about 600 mW. We show that cascaded parametric interaction has a strong impact on squeezing and phase-sensitive extinction ratio and that this depends on the dispersion profile of the waveguide.Phase-sensitive parametric interactions can selectively process the two complex quadratures of the optical field.

Nonlinear spectroscopy of the Jaynes–Cummings molecule

Of particular interest in quantum optics is the study of atom-cavity interactions in the strong coupling regime in which an intracavity photon is likely to be absorbed and reemitted before escaping into the external environment. We have recently achieved conditions appropriate to this regime in an apparatus consisting of a beam of Cesium atoms coupled to an optical resonator of finesse 330,000 and length 0.35 mm.
