摘要: A cryostat socket for holding an ion trap device mounted on a substrate in a cryostat includes a frame having a heat removal surface configured to be thermally coupled to a laterally outer region of the device carrier. The cryostat socket further includes a cover configured to exert a compressive force on the front side of the device carrier when assembled with the frame, by which the rear side of the device carrier is thermally coupled to the heat removal surface.

摘要: A micro-fabricated device for controlling trapped ions includes a substrate of a dielectric material or a semiconductor material. A structured electrode layer is disposed above the substrate. The structured electrode layer forms a plurality of electrodes of an ion trap configured to trap ions in a space above the structured electrode layer. The structured electrode layer includes a low phonon density of states layer, referred to as low-PDOS layer, the low-PDOS layer being of TiN or TiW or Ti or W and having a thickness of equal to or greater than 100 nm.

摘要: A micro-fabricated device for controlling trapped ions includes a first substrate having a main surface. A structured first metal layer is disposed over the main surface of the first substrate. The structured first metal layer includes electrodes of at least one ion trapping zone configured to trap an ion in a space above the structured first metal layer. A dielectric element is fixedly attached to the first substrate. The dielectric element includes at least one short-pulse-laser direct written (SPLDW) waveguide configured to direct laser light towards an ion trapped in the at least one ion trapping zone.

摘要: A device for controlling trapped ions includes a first substrate and a second substrate spaced apart from the first substrate. The device further includes at least one ion trap configured to trap an ion in a space between the first substrate and the second substrate. DC electrodes of the ion trap are formed on the first substrate. RF electrodes of the ion trap are formed on the second substrate and not on the first substrate.

摘要: A device for controlling trapped ions includes a substrate. A structured first metal layer is disposed over the substrate. The structured first metal layer forms electrodes of an ion trap configured to trap ions in a space above the structured first metal layer. The structured first metal layer is formed of a multilayer stack. The multilayer stack includes an electrically conductive layer of a first material and a mechanical stabilization layer of a second material. The second material has an elastic modulus greater than the elastic modulus of the first material and/or the second material has a yield strength greater than the yield strength of the first material.

摘要: A device for controlling trapped ions includes a substrate. A metal layer is disposed over the substrate. An electrode of an ion trap is disposed over the metal layer, the electrode being configured to trap one or more ions in a space above the electrode. An electrical insulator is disposed between the metal layer and the electrode. The electrical insulator has an upper surface facing towards the electrode and a lower surface facing towards the metal layer. An etching rate of the electrical insulator increases along a direction pointing from the upper surface to the lower surface.

摘要: A micro-fabricated device for controlling trapped ions includes a substrate. A structured electrode layer is disposed over the substrate. The structured electrode layer forms a plurality of electrodes of an ion trap configured to trap ions in a space above the structured electrode layer. The structured electrode layer is formed of a multilayer stack. The multilayer stack includes an electrically conductive smoothing layer having a planarized surface and an electrically conductive top layer disposed over the planarized surface of the smoothing layer. The top layer provides an exposed surface of the structured electrode layer, the exposed surface having a mean surface roughness equal to or less than Ra=5 nm.
