• Abstract: We describe the design, commissioning and operation of an ultra-low-vibration closed-cycle cryogenic ion trap apparatus. One hundred lines for low-frequency signals and eight microwave / radio frequency coaxial feed lines offer the possibility of implementing a small-scale ion-trap quantum processor or simulator. With all supply cables attached, more than 1.3 W of cooling power at 5 K is still available for absorbing energy from electrical pulses introduced to control ions. The trap itself is isolated from vibrations induced by the cold head using a helium exchange gas interface. The performance of the vibration isolation system has been characterized using a Michelson interferometer, finding residual vibration amplitudes on the order of 10 nm rms. Trapping of $^9$Be$^+$ ions has been demonstrated using a combination of laser ablation and photoionization.

  We report on a coupled cavity configuration in which a superconducting cavity is coupled with a high permittivity resonator. The sensitivities of such configurations are discussed both in strong coupling and weak coupling regime. These results highlight the potential of the coupled resonator systems as microwave sensors and are useful for the engineering of high permittivity resonators for applications at cryogenic temperatures.

  A superconducting quantum interference device is embedded in a microwave resonator and coupled via a pick-up loop to a magnetically-levitated superconducting sphere. The motion of the sphere in the magnetic trap induces a frequency shift in the SQUID-cavity system. The measured displacement sensitivity of $10-7, mathrmm / sqrtmathrmHz$, defines a path towards ground-state cooling of levitated particles with Planck-scale masses at millikelvin environment temperatures.

• High stability cryogenic system for quantum computing with compact packaged ion traps [0.0]
  Cryogenic environments benefit ion trapping experiments by offering lower motional heating rates, collision energies, and an ultra-high vacuum (UHV) environment for maintaining long ion chains for extended periods of time. Here, we present a novel ion trapping system where a commercial low-vibration closed-cycle cryostat is used in a custom monolithic enclosure. We packaged a surface ion trap in a cryo-package assembly that enables easy handling, while creating a UHV environment for the ions.

We reach the lowest temperature reported for a highly charged ion, with a residual temperature of only $Tlesssim200mathrmmu K$ in each of the two modes.
