Quantum device with coplanar waveguide for quantum applications
A recently granted patent (Publication Number: US11889770B2) discloses a quantum device comprising a coplanar waveguide with a central conductor line situated between two return conductor lines on a substrate. The central conductor line includes base conductor portions directly on the substrate and bridge portions raised above the base conductor portions, forming defined gaps to reduce energy loss associated with the substrate. The device is designed to meet specific circuit design criteria without exceeding a threshold distance, enhancing its efficiency in quantum computing applications.
Furthermore, the patent includes methods and computer program products for forming the quantum device, emphasizing the use of superconducting materials and dielectric substrates with specific thermal conductivity levels. The coplanar waveguide structure, part of a quantum computing circuit that may include qubits, aims to optimize performance by minimizing energy loss and maintaining precise distances between components. The system described in the patent involves memory storing computer-executable components and a processor to execute these components, facilitating the creation of quantum computing circuits with coplanar waveguides designed for efficient operation in quantum computing environments. Overall, the patent highlights advancements in quantum device design and fabrication techniques to enhance the functionality and performance of quantum computing systems.
