Nonlinear optical devices as single-photon quantum frequency converters
Abstract/Contents
- Abstract
- Appropriate interfaces between quantum nodes and low-loss quantum channels in long-distance quantum communication networks and upconversion-assisted SPDs are based on quantum frequency conversion (QFC) processes. QFC processes give us the ability to translate the qubit's carrier frequency while its quantum state is maintained. The primary interest of QFC has been upconversion single-photon detection. A process where a single-photon level signal in the telecommunications band is upconverted to a visible wavelength and use the well-developed single-photon detectors based on silicon avalanche photodiodes. The need for an interface between coherently controlled matter qubits (which typically have optical transitions in the visible or near-infrared spectral range) and low-loss photonic quantum channels (at the 1.3 or 1.5 m bands in silica optical fibers) is a primary challenge toward developing a long-distance hybrid quantum network. The possibility of making such an interface based on nonlinear interactions is another motivation to develop QFC processes. We can reach high conversion efficiency by using reverse-proton-exchange waveguides. A key issue in these devices is minimizing the generation of noise photons in the signal band by inelastic scattering of the pump. The two primary origins for this noise processes are known as spontaneous parametric down conversion (SPDC) and spontaneous Raman scattering (SRS). It has been shown that long-wavelength-pumping dramatically reduce the dark-count rate. This requirement limits the wavelength-translation range which can be achieved in a single conversion step. This constraint led to the development of integrated devices based on two cascaded parametric conversion processes. We discuss considerations in using cascaded frequency mixers for low-noise quantum frequency conversion between two widely disparate frequencies, such as long-wavelength-pumped down-conversion of visible single photons from a diamond nitrogen-vacancy center or trapped ion to 1550 nm. We have demonstrated an integrated architecture for low-noise, low power cascaded quantum frequency conversion from 649.7 nm to 1595 nm. The results presented in this dissertation represent a critical step toward low-power, low-noise quantum frequency conversion for long distance quantum communication networks.
