Optomechanics driven by noisy and narrowband fields

Louise Banniard, Cheng Wang, Davide Stirpe +4

We report a study of a cavity optomechanical system driven by narrow-band electromagnetic fields, which are applied either in the form of uncorrelated noise, or as a more structure…

Degeneracy-breaking and Long-lived Multimode Microwave Electromechanical Systems Enabled by Cubic Silicon-Carbide Membrane Crystals

Yulong Liu, Huanying Sun, Qichun Liu +3

Cubic silicon-carbide crystals (3C-SiC), known for their high thermal conductivity and in-plane stress, hold significant promise for the development of high-quality () mechanica…

Coupling high-overtone bulk acoustic wave resonators via superconducting qubits

Wayne Crump, Alpo Välimaa, Mika A. Sillanpää

In this work, we present a device consisting of two coupled transmon qubits, each of which are coupled to an independent high-overtone bulk acoustic wave resonator (HBAR). Both HBA…

Quantum backaction evading measurements of a silicon nitride membrane resonator

Yulong Liu, Jingwei Zhou, Laure Mercier de Lépinay +1

Quantum backaction disturbs the measurement of the position of a mechanical oscillator by introducing additional fluctuations. In a quantum backaction measurement technique, the ba…

Optomechanical Anti-lasing with Infinite Group Delay at a Phase Singularity

Yulong Liu, Qichun Liu, Shuaipeng Wang +3

Singularities that symbolize abrupt changes and exhibit extraordinary behavior are of broad interest. We experimentally study optomechanically induced singularities in a compound s…

Multiphonon transitions in a quantum electromechanical system

Alpo Välimaa, Wayne Crump, Mikael Kervinen +1

We investigate a superconducting qubit coupled to a quantum acoustic system in a near resonant configuration. In our system we measure multiphonon transitions, whose spectrum revea…
