The short version
- Superinductors are electrical inductors that are engineered to have an extremely large inductance, often far beyond what can be achieved with conventional coils.
- They are particularly important for superconducting qubits and quantum circuits, as a large inductance can dramatically alter the circuit's quantum behavior.
- This makes superinductors interesting for quantum technology, as they enable the creation of circuits with very large impedance and very small inductive energy scales.
What happened
In this work, researchers show that superconducting circuit elements can be fabricated with a commercial CMOS process by utilizing titanium nitride (TiN). TiN is particularly well suited for this purpose because of its high kinetic inductance, which makes it possible to create compact, high-inductance circuit elements while maintaining robust superconducting properties.
Why it matters
The work has reported the development of a nonlinear superinductor within a silicon integrated circuit.
