A quantum gate between the ions can be implemented using electric fields.

One is a so-called trapped-ion platform, one of the most promising candidates for quantum computing that makes use of ions - atoms that have either a surplus or a shortage of electrons and as a result are electrically charged.

As the name suggests, trapped-ion quantum computers use a crystal of trapped ions.

The homogeneity of the electric field assures that it will only allow the two ions to move together with all other ions in the crystal.

As a result, the interaction strength between the two selected ions is fixed, regardless of how far apart the two ions are.

As a result, this scheme for quantum computing is inherently scalable, and compared to other state-of-the-art quantum computing schemes poses fewer technical challenges for achieving comparably well-operating quantum computers.
