Although the strengths of optical non-linearities available experimentally have been rapidly increasing in recent years, significant challenges remain to using such non-linearities to produce useful quantum devices such as efficient optical Bell state analysers or universal quantum optical gates. Here we describe a new approach that avoids the current limitations by combining strong non-linearities with active Gaussian operations in efficient protocols for Bell state analysers and Controlled…

Large Purcell enhancement with nanoscale non-reciprocal photon transmission in chiral gap-plasmon-emitter systems.

A gap-plasmon-emitter system demonstrating large Purcell enhancement with effective nanoscale non-reciprocal photon transmission offers an efficient way for photon routing in optical circuits and quantum networks and also extends methods for manipulating non-Reciprocal devices.

Roadmap on all-optical processing

The Roadmap is organized so as to put side by side contributions on different aspects of optical processing, aiming to enhance the cross-contamination of ideas between scientists working in three different fields of photonics: optical gates and logical units, high bit-rate signal processing and optical quantum computing.
