A superconducting qubit with noise-insensitive plasmon levels and decay-protected fluxon states

Farid Hassani, Matilda Peruzzo, Lucky N. Kapoor +3 more

The inductively shunted transmon (IST) is a superconducting qubit with exponentially suppressed fluxon transitions and a plasmon spectrum approximating that of the transmon. It shares many characteristics with the transmon but offers charge offset insensitivity for all levels and precise flux tunability with quadratic flux noise suppression. In this work we propose and realize IST qubits deep in the transmon limit where the large geometric inductance acts as a mere perturbation. With a flux dispersion of only 5.1 MHz we reach the 'sweet-spot everywhere' regime of a SQUID device with a stable coherence time over a full flux quantum. Close to the flux degeneracy point the device reveals tunneling physics between the two quasi-degenerate ground states with typical observed lifetimes on the order of minutes. In the future, this qubit regime could be used to avoid leakage to unconfined transmon states in high-power read-out or driven-dissipative bosonic qubit realizations. Moreover, the combination of well controllable plasmon transitions together with stable fluxon states in a single device might offer a way forward towards improved qubit encoding schemes.

Structural Instability of Driven Josephson Circuits Prevented by an Inductive Shunt

Lucas Verney, Raphaël Lescanne, Michel Devoret +2 more

Strongly driven superconducting circuits are a versatile platform to implement a multitude of Hamiltonians for quantum computation, simulation, and sensing. Unfortunately, they can display complex dynamics with instabilities, so predicting and preventing these instabilities is crucial for applications. This paper proposes an inductively shunted transmon qubit as the elementary circuit optimized for strong parametric drives. Developing a numerical approach that avoids the limitations of perturbative analysis, the authors demonstrate that adding the inductive shunt significantly extends the range of pump powers in which the circuit is stable.
