About PICC

In the quest for the realization of quantum information processors,  trapped ions occupy a prominent position. The challenge of realizing large-scale processors and quantum simulators based on ions will,  however, require that one deals with more complex structures, which may include mesoscopic ordered ion ensembles, i.e., ion Coulomb crystals. In this regime, it is expected that the effect of noise will grow in importance and the control techniques, which have been so   successfully applied to small numbers of ions, will be inefficient.  This raises the timely issue of identifying novel and efficient strategies for controlling the quantum dynamics and manipulating the quantum state of ion Coulomb crystals

The PICC proposal represents a joint theoretical and experimental effort whose aims are

• to identify tools for controlling ion crystals as their size is scaled up,
• to develop strategies for implementing controlled quantum dynamics of mesoscopic ion Coulomb crystals in a noisy environment and
• to explore the capability of ion Coulomb crystals as quantum simulators.

The long-term vision underlying this proposal is to engineer quantum correlations and entanglement in ion Coulomb crystals in order to exploit them for technological purposes of different kinds.

It is expected that this effort will pave the way for what could be the realization of the first specific-purpose, large scale quantum processors, complementing existing efforts with the alternative system of neutral atoms in optical lattices.
