摘要： Electron trap device 1 comprises a cryogenic apparatus 40, a superconducting circuit 10 and a heat bath 60. The superconducting circuit 10 and the heat bath 60 are placed within the cryogenic apparatus 40. This allows the superconducting circuit 10 to operate and the heat bath 60 to be maintained at a constant low temperature, e.g., about 20 mK. The superconducting circuit 10 comprises a cooling resonator 20, a microwave resonator 22 and an electron trap region 50. The superconducting circuit 10 comprises a microstructure in which the opposing electrodes are arranged in a position that is linear symmetrical to the center line through the electron trap region and surrounded by a superconductor, such that the electron trap region 50 comprises a plurality of opposing electrodes.

摘要： A micro-fabricated device (100, 200, 400) for controlling trapped ions (180) includes a substrate (120) of a dielectric material or a semiconductor material. A structured electrode layer is disposed above the substrate. The structured electrode layer (125) 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.
