Physicists at the University of Amsterdam in the Netherlands have proposed a new scalable quantum computing architecture using trapped ions.
The technique employs a trapped-ion platform manipulated by optical tweezers and oscillating electric fields.
The researchers applied a uniform electric field to an entire crystal of trapped ions, in order to control interactions between two ions selected via application of tweezer potentials.
These interactions are not dependent on the distance between them, so the duration of a quantum gate's operation also is independent. This grants the architecture inherent scalability, and can confer operational performance comparable to other state-of-the-art quantum systems while presenting fewer technical hurdles.
