Original Abstract Submitted

the technology provides fluorescent readout of microwave-type qubits using a paracoupler architecture. a quantum computing system comprises a set of qubits configured to be responsive to one or more microwave signals and a control apparatus configured to apply the one or more microwave signals to the set of qubits. the control apparatus includes a set of control lines configured to transmit the one or more microwave signals to corresponding ones of the set of qubits. the system also includes a readout apparatus configured to perform qubit measurements. the readout apparatus including a readout line operatively coupled to the qubits. a paracoupler operatively arranged between the set of qubits and the readout apparatus is configured to enable parametric fluorescent readout of the qubits via the readout apparatus. when the paracoupler is not driven it prevents coupling of the qubits with the readout line.
