Abstract: A device comprises first and second qubits, and a qubit coupler coupled between the first and second qubits. The second qubit comprises first and second modes with the first mode configured to store data. The qubit coupler comprises first and second modes, and operates in a first state or second state. In the first state, the first qubit is exchange coupled to the first mode of the qubit coupler, and the second mode of the second qubit is exchange coupled to the second mode of the qubit coupler, to suppress interaction between the first and second qubits. In the second state, the first qubit and the first mode of the second qubit are exchange coupled to both the first and second modes the qubit coupler, to enable interaction between the first and second qubits for an entanglement gate operation in response to a control signal applied to the qubit coupler.

Abstract: Embodiments include techniques for transmitting and receiving radio frequency (RF) signals, where the techniques for generating, via a digital analog converter (DAC), a frequency signal, and filtering the frequency signal to produce a first filtered signal and a second filtered signal. The techniques also include transmitting the second filtered signal to a device under test and filtering the second filtered signal into a sub-signal having one or more components. The techniques include mixing the first filtered signal with the sub-signal to produce a first mixed signal, subsequently mixing the first mixed signal with an output signal received from the device under test to produce a second mixed signal and converting the second mixed signal for analysis.
