Device for controlling an ion, method for forming the same, and method for controlling the same

A method for forming a device for controlling an ion, the method comprising:

• forming an electrode arrangement configured to generate an electric field to trap the ion, wherein a plurality of openings are defined in the electrode arrangement;
• and
• forming an optical arrangement configured to transmit a plurality of output optical signals of different wavelengths to the trapped ion to control the trapped ion,
• wherein forming the optical arrangement comprises forming a plurality of wavelength filters configured to receive at least one input optical signal, wherein, for each wavelength filter of the plurality of wavelength filters, the wavelength filter is configured to filter the at least one input optical signal to generate a respective output optical signal of the plurality of output optical signals, and wherein the optical arrangement is configured to transmit the respective output optical signal to the trapped ion through a respective opening of the plurality of openings, the respective output optical signal being defined by a respective wavelength of the different wavelengths.
