Abstract
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.
Claims13
An apparatus for exciting a trapped ion comprising:
- a laser unit configured to emit a first laser beam and a second laser beam, the first laser beam having a first frequency and the second laser beam having a second frequency, wherein the first frequency is different from the second frequency;
- an objective configured to focus the first laser beam and the second laser beam at a position of a trapped ion, wherein the first laser beam and the second laser beam pass through at least one common lens within the objective;
- and
- a controller configured to control said laser unit to generate a moving standing wave at the position of the trapped ion, which induces a force on the trapped ion, using the first laser beam and the second laser beam.
A method for exciting a trapped ion, comprising:
- generating a first laser beam and a second laser beam, the first laser beam having a first frequency and the second laser beam having a second frequency, the first frequency being different from the second frequency, the first laser beam and the second laser beam being focused at a position of a trapped ion, wherein the first laser beam and the second laser beam pass through at least one common lens within an objective;
- and
- generating a moving standing wave at a position of the trapped ion, which induces a force on the trapped ion, using the first laser beam and the second laser beam.
