摘要： Some embodiments in the present disclosure relate to an apparatus and methods to excite a trapped ion. A first laser beam and a second laser beam pass through at least one common lens of an objective. The two laser beams are focused by said objective at the position of the trapped ion. A moving standing wave is generated at the position of the trapped ion, which induces a force on the trapped ion. Two ions may be entangled by generating such moving standing wave at the respective positions of both of said ions.

摘要： Provided is a method of reducing the magnitude of a quasi-static electric dipole field at the null position of an oscillating electric quadrupole field of an ion trap. The method includes trapping at least one ion in a trapping electric field. The trapping electric field includes an electric field amplitude; using an interferometry sequence including applying a first laser pulse when the trapping electric field amplitude includes a first trapping electric field amplitude; applying a second laser pulse when the trapping electric field amplitude includes a second trapping electric field amplitude different from the first electric field amplitude; and measuring a state of the ion; repeating the interferometry sequence in order to obtain a plurality of measurements of the state of the ion; determining a probability that the trapped ion changes state; and adjusting the trapping electric field based on the determined probability.

摘要： A scalar magnetometer includes a sensor element, a circuit carrier, a pump radiation source, a radiation receiver and evaluation means. The pump radiation source emits pump radiation. The sensor element preferably includes one or more NV centers in diamond as paramagnetic centers. This paramagnetic center emits fluorescence radiation when irradiated with pump radiation. The radiation receiver converts a intensity signal of the fluorescence radiation into a receiver output signal. The evaluation means detects and/or stores and/or transmits the value of the receiver output signal. The material of the circuit carrier is preferably transparent for the pump radiation in the radiation path between pump radiation source and sensor element and transparent for the fluorescence radiation in the radiation path between sensor element and radiation receiver. The components sensor element, pump radiation source, radiation receiver and evaluation means are preferably mechanically attached to the circuit carrier.
