Beschreibung
Zusammenfassung:	Various embodiments for precise and accurate delivery, in terms of position, frequency, and/or phase, of one or more lasers to an atomic system are provided. In a first embodiment, a gate laser system for a trapped ion quantum computer comprising a first and second laser are provided. The first and second lasers are frequency locked to a first and second frequency of a frequency comb, respectively. The first and second lasers are each configured to provide laser beams to a qubit ion within an ion trap of the quantum computer to provide a gate. In another embodiment, a qubit ion and sympathetic ion management system for a trapped ion quantum computer comprising a first, second, and third laser is provided. Each laser is locked to a different frequency of a frequency comb, and provide one or more laser beams to an ion trap of the quantum computer.
