  • Organic thin-film quantum sources
    Patent number: 11977317
    Abstract: A photon source for generating entangled photons includes a pump laser, and 4-N, N-dimethylamino-4?-N?-methyl-stilbazolium-tosylate (DAST) crystals, the pump laser pumping the DAST crystals with pump photons to generate a stream of pairs of entangled photons, each pair comprising a signal photon and an idler photon.
    Type: Grant
    Filed: February 16, 2023
    Date of Patent: May 7, 2024
    Assignee: Brown University

  • ULTRA-LOW NOISE CRYOGENIC MICROWAVE AMPLIFICATION
    Publication number: 20230327388
    Abstract: Embodiments of the microwave amplification system are described. In an embodiment, a microwave amplification system includes a microwave amplifier that contains a paramagnetic material with an impurity. The impurity has a plurality of nuclear spin and electron spin-based energy levels. The system includes an input to receive a pumping signal which is transmitted to the microwave amplifier to cause a population inversion in the impurity and excite it to one of the nuclear spin and electron spin-based energy levels. The system further includes another input to receive an input signal to be amplified by the microwave amplifier, the input signal having a lower power than the pumping signal. Once transmitted to the microwave amplifier, the input signal is amplified by the excited state of the impurity in the microwave amplifier thereby generating an amplified signal.
