摘要： One example includes a superconducting phase-shift system. The system includes an all-pass filter comprising at least one variable inductance element. The all-pass filter can be configured to receive an input signal and to provide the input signal as an output signal that is phase-shifted relative to the input signal based on a variable inductance provided by each of the at least one variable inductance element. The system can further include a phase controller configured to provide a phase-control current to control the variable inductance of the at least one variable inductance element based on a characteristic of the phase-control current.

摘要： A superconducting switch system is provided that includes a filter network having a first SQUID coupled to a second SQUID via a common node, an input port coupled to the common node, a first output port coupled to the first SQUID, and a second output port coupled to the second SQUID. The superconducting switch system also includes a switch controller configured to control an amount of induced current through the first SQUID and the second SQUID to alternately switch the first and second SQUIDS between first inductance states in which a desired bandwidth portion of a signal provided at the input terminal passes to the first output terminal and is blocked from passing to the second output terminal, and second inductance states in which the desired bandwidth portion of the input signal passes to the second output terminal and is blocked from passing to the first output terminal.

摘要： A tunable bus-mediated coupling system is provided that includes a first input port coupled to a first end of a variable inductance coupling element through a first resonator and a second input port coupled to a second end of the variable inductance coupling element through a second resonator. The first input port is configured to be coupled to a first qubit, and the second output port is configured to be coupled to a second qubit. A controller is configured to control the inductance of the variable inductance coupling element between a low inductance state to provide strong coupling between the first qubit and the second qubit and a high inductance state to provide isolation between the first qubit and the second qubit.

摘要： A superconducting switch system is provided that includes a filter network having an input portion and an output portion, and a variable inductance coupling element that couples the input portion to the output portion. The variable inductance coupling element has a first inductance that allows a desired portion of an input signal to pass from the input portion to the output portion as an output signal, and a second inductance state that suppresses the input signal from passing from the input portion to the output portion. The superconducting switch system further comprises a switch controller configured to control the switching of the variable inductance coupling element between the first inductance state and the second inductance state.

摘要： Systems and methods are provided for reading an associated state of a qubit. A first soliton is injected along a first Josephson transmission line coupled to the qubit. A velocity of the first soliton is selected according to a physical length of the qubit and a characteristic frequency of the qubit. A second soliton is injected at the selected velocity along a second Josephson transmission line that is not coupled to the qubit. A delay associated with the first soliton is determined relative to the second soliton.
