Hybrid quantum information processing

Understand

The development of quantum information processing has traditionally followed two separate and not immediately connected lines of study.

• The main line has focused on the implementation of quantum bit (qubit) based protocols whereas the other line has been devoted to implementations based on high-dimensional Gaussian states (such as coherent and squeezed states).
• The separation has been driven by the experimental difficulty in interconnecting the standard technologies of the two lines.
• However, in recent years, there has been a significant experimental progress in refining and connecting the technologies of the two fields which has resulted in the development and experimental realization of numerous new hybrid protocols.
