An apparatus includes a main body, circuit assembly, lens, and clamping assembly. The main body includes an aperture that receives a wafer configured to receive a sample under study. The main body is configured to support the circuit assembly, which includes illumination sources that emit light of different colors such that total internal reflection is generated in the wafer. The main body is configured to provide support for the lens, and the clamping assembly mechanically coupled to the main body such that the lens is selectively positionable with respect to a camera lens. A microscopy imaging apparatus includes an illumination source, wafer, and charge-coupled device. The illumination source is configured to emit white light such that total internal reflection is generated in the wafer. The sample under study is disposed between the wafer and the charge coupled device, and the charge coupled device is configured to obtain an image of the sample under study upon illumination of the wafer by the illumination source.

A qubit device for use in a quantum computing environment includes a semiconductor substrate, an insulating layer disposed on at least a portion of an upper surface of the substrate, and a transition metal silicide (TMSi) heterojunction disposed on at least a portion of an upper surface of the insulating layer. The TMSi heterojunction includes a link layer and at least first and second TMSi regions coupled with the link layer. The link layer may include a normal conductor, thereby forming a superconductor-normal conductor-superconductor (SNS) junction, or a geometric constriction, thereby forming a superconductor-geometric constriction-superconductor (ScS) junction. The link layer may form at least a portion of a channel including intrinsic or doped silicon.
