Abstract
Claims20
A stripline circulator comprising:
- a first ground structure having one or more cavities;
- one or more dielectrics inside the one or more cavities;
- at least one center conductor;
- a first port;
- a second port;
- and
- a third port;
- wherein the stripline circulator is characterized by non-reciprocal signal transmission behavior comprising:
- responsive to a first signal being provided as an input signal to the first port, the second port provides the first signal as an output signal;
- and
- responsive to a second signal being provided as the input signal to the second port, the third port provides the second signal as the output signal.
8 more elements
A quantum computing system comprising:
- a plurality of qubits;
- a quantum logic circuit configured to perform one or more quantum operations on the plurality of qubits;
- and
- a stripline circulator, wherein the stripline circulator comprises:
- a first ground structure having one or more cavities;
- one or more dielectrics inside the one or more cavities;
- and
- at least one center conductor.
5 more elements
A method for tuning a stripline circulator, comprising:
- adjusting a contact pressure between a first ground of the stripline circulator and a second ground of the stripline circulator, such that an impedance between the first ground and the second ground is increased or reduced.
