FIELD: quantum computing.
SUBSTANCE: proposed device for transmission of microwave radiation from a coplanar resonator to at least two superconducting qubits allows for not only minimization of a size of a quantum system on a chip, but also expansion of its functional capabilities, as the same coplanar resonator can both transmit microwave radiation to superconducting qubits and read states of at least two qubits connected by a capacity element. In addition, a technology of production of quantum systems is simplified, as a stage of determination of location of qubits with resonators on a transmission line is eliminated.
EFFECT: invention is aimed at simplification of a structure of a device for transmission of microwave radiation from a thin-film coplanar microwave resonator to superconducting qubits and reading states on a chip, while expanding its functional capabilities.
