Title:
ION TRAP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/135086
Kind Code:
A1
Abstract:
An ion trap system, comprising a laser regulation module (11) used for dividing beams into P first beams and Q second beams, wherein N first beams in the P first beams are respectively transmitted to N ions (121), and M second beams in the Q second beams are respectively transmitted to M monitoring units (122); the M monitoring units (122) used for respectively detecting the M second beams, and respectively obtaining the spatial intensity distribution information of the M second beams; and a feedback control module (13) used for receiving the spatial intensity distribution information of the M second beams, determining N first control signals according to the spatial intensity distribution information of the M second beams, and transmitting the N first control signals to the laser regulation module (11), wherein the N first control signals have one-to-one correspondence to the N first beams, and each first control signal is used for controlling the laser regulation module (11) to align a corresponding first beam with the ion (121). Therefore, the present invention facilitates improving the degree of alignment of the first beam and the corresponding ion (121), thereby improving the fidelity of performing quantum state control on the ion (121).
