US Patent 10900998 Contactless screening of a qubit

Systems, devices, computer-implemented methods, and computer program products to facilitate contactless screening of a qubit are provided. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a scanner component that establishes a direct microwave coupling of a scanning probe device to a qubit of a quantum device. The computer executable components can further comprise a parameter extraction component that determines qubit frequency of the qubit based on the direct microwave coupling.
