Abstract: A single-photon-spectroscopic isotope detector. In some embodiments, the isotope detector includes a narrow-band light source, and a single-photon detector. The narrow-band light source may be configured to generate light at a first wavelength near a second wavelength corresponding to a vibrational mode of a molecule including an isotope of interest.

Abstract: A van der Waals capacitor and a qubit constructed with such a capacitor. In some embodiments, the capacitor includes a first conductive layer; an insulating layer, on the first conductive layer; and a second conductive layer on the insulating layer. The first conductive layer may be composed of one or more layers of a first van der Waals material, the insulating layer may be composed of one or more layers of a second van der Waals material, and the second conductive layer may be composed of one or more layers of a third van der Waals material.

Abstract: An evaporatively cooled device and a system including the same. In some embodiments, the system includes an oligolayer conductive sheet; a superconductor; a tunneling barrier, between the oligolayer conductive sheet and the superconductor; and a bias circuit, configured to apply a bias voltage across the tunneling barrier, the bias voltage being less than a gap voltage of the superconductor and greater than one-half of the gap voltage of the superconductor.
