Developing micro- and nanomechanical systems with ultralow dissipation is a key avenue for exploring quantum nanomechanics. Exploiting a superfluid Helmholtz resonance in liquid helium, the authors build a resonator with a quality factor of 9×10⁵, with the potential to reach 10⁸. Its frictionless flow, low dielectric losses, large thermal conductivity, and micrometer-scale confinement make this mesoscopic system a promising tool to study mechanics and optomechanics at the quantum-to-classical crossover.
