Abstract: Quantum circuit assemblies that employ active pulse shaping in order to be able to control states of a plurality of qubits with signal pulses propagated over a shared signal propagation channel are disclosed. An example quantum circuit assembly includes a quantum circuit component that includes a first qubit, associated with a first frequency to control the state of the first qubit, and a second qubit, associated with a second frequency to control the state of the second qubit. A shared transmission channel is coupled to the first and second qubits. The assembly further includes a signal pulse generation circuit, configured to generate a signal pulse to be propagated over the shared transmission channel to control the state of the first qubit, where the signal pulse has a center frequency at the first frequency, a bandwidth that includes the second frequency, and a notch at the second frequency.

Abstract: Systems and methods for synchronizing operation of control circuits in quantum circuit assemblies are disclosed. An example assembly for controlling operation of a qubit device includes a plurality of control circuits and an event synchronization arrangement. The plurality of control circuits may include a first and a second control circuits, configured to perform, respectively, first and second actions to control operation of the qubit device. The event synchronization arrangement may be used to control operation of the plurality of control circuits to provide to the second control circuit an indication that the first control circuit performed the first action, and to configure the second control circuit to perform the second action in response to receiving the indication that the first control circuit performed the first action. Assemblies disclosed herein provide improved control over qubits, good scalability in the number of qubits included in the device, and/or design flexibility.
