Few-photon degenerate parametric resonance in a two-tone driven microwave resonator
Orjan Ameye, Jakob Koenig, Clinton Potts +2
Multi-tone external driving offers a route to parametric physics without directly modulating the device. However, the validity of the parametric response in the few-photon regime r…
Suppressing Cavity Frequency Noise Using a Kerr Nonlinearity
J. P. van Soest, S. Meilof, G. L. Bhai +3
Resonance-frequency fluctuations can limit the sensitivity and stability of superconducting microwave cavities used for qubit readout, optomechanical displacement sensing, and magn…
Higher Josephson harmonics in a tunable double-junction transmon qubit
Ksenia Shagalov, David Feldstein-Bofill, Leo Uhre Jakobsen +11
Tunable Josephson harmonics open new avenues for qubit design. We demonstrate a superconducting circuit element consisting of a tunnel junction in series with a SQUID loop, yieldin…
Flux-modulated tunable interaction regimes in two strongly nonlinear oscillators
J. D. Koenig, G. Barbieri, F. Fani Sani +3
The ability to efficiently simulate a variety of interacting quantum systems on a single device is an overarching goal for digital and analog quantum simulators. In circuit quantum…
Magnon-magnon interaction induced by nonlinear spin wave dynamics
Matteo Arfini, Alvaro Bermejillo-Seco, Artem Bondarenko +4
We experimentally and theoretically demonstrate that nonlinear spin-wave dynamics can induce an effective resonant interaction between non-resonant magnon modes in a yttrium iron g…

Magnon-microwave backaction noise evasion in cavity magnomechanics
V. A. S. V. Bittencourt, C. A. Potts, J. P. Davis +1
In cavity magnomechanical systems, magnetic excitations couple simultaneously with mechanical vibrations and microwaves, incorporating the tunability of magnetism and the long life…
Generation of Large Amplitude Phonon States in Quantum Acoustics
C. A. Potts, W. J. M. Franse, V. A. S. V. Bittencourt +2
The development of quantum acoustics has enabled the cooling of mechanical objects to their quantum ground state, generation of mechanical Fock-states, and Schrodinger cat states.…
Three-Tone Coherent Microwave Electromechanical Measurement of a Superfluid Helmholtz Resonator
Sebastian Spence, Emil Varga, Clinton A. Potts +1
We demonstrate electromechanical coupling between a superfluid mechanical mode and a microwave mode formed by a patterned microfluidic chip and a 3D cavity. The electric field of t…
Multi-Tone Microwave Locking via Real-Time Feedback
J. P. van Soest, C. A. Potts, S. Peiter +2
Environmental noise coupling to mechanical experiments often introduces low-frequency fluctuations to the resonators, adding noise to measurements and reducing signal to noise. To…
