Trapped ion chain as a neural network: error resistant quantum computation

Phys Rev Lett. 2007 Jan 12;98(2):023003. doi: 10.1103/PhysRevLett.98.023003. Epub 2007 Jan 9.

Abstract

We demonstrate the possibility of realizing a neural network in a chain of trapped ions with induced long range interactions. Such models permit one to store information distributed over the whole system. The storage capacity of such a network, which depends on the phonon spectrum of the system, can be controlled by changing the external trapping potential. We analyze the implementation of error resistant universal quantum information processing in such systems.
