Latest Patents

Carlos holds a patent for "Spectrally multiplexed solid state quantum emitters and memories for quantum repeaters." This innovative technology utilizes a spectrally multiplexed quantum repeater (SMuQR) that is based on spatially arrayed nodes of frequency-multiplexed multi-qubit registers. The invention leverages the natural inhomogeneous distribution of optical transition frequencies in solid-state defect centers. This allows for the spectrally selective, individual addressing of numerous defect centers within an optical diffraction-limited spot along a long cavity or waveguide. The technology enables frequency shifting of an incident optical field at a rate as fast as once per defect center lifetime. The defect centers resonate at visible frequencies and emit single photons, which are down-converted to a wavelength suitable for long-distance transmission via conventional optical fiber. The down-converted photons are all at the same telecommunications wavelength, with different spectral bins mapped to different temporal bins to maintain multiplexing in the time domain for distribution to other nodes in the quantum network.
