About this Research Topic
We are on the dawn of the second quantum revolution wherein human beings are manipulating the inherent properties of quantum mechanics to develop a wide variety of novel technologies. Photons are nearly ideal carriers of quantum information (flying quantum bits), due to their weak interaction with environments and relatively long coherence time. Owing to these outstanding characteristics, they are widely implemented not only in constructing quantum computing, but also in developing quantum communication. Quantum technologies based on photons will potentially require integrated optical architecture for improved performance, such as easy miniaturization and good scalability.
Although plenty of experiments on quantum information have been performed with bulk optics, for those complicated schemes, they will inevitably suffer from severe drawbacks, such as poor stability, quite limited operation precision and rather bulky physical size etc. One promising candidate on conquering these weaknesses is to adopt miniaturized optical integrated devices. Until today, a large number of great researches on this aspect have been issued on different platforms.
The aim of this Research Topic is to display the state of the art, compare different technologies, feature new directions, and outline prospects of this field. This Research Topic will therefore cover:
- Quantum optics,
- Quantum information,
- Quantum simulation and computing
- Main building blocks of an integrated photonic quantum circuits (single photon sources, entangled photon sources, single photon detectors, linear optical devices, quantum interference devices, and materials and processing to manufacture integrated quantum devices)
- Integrated quantum circuits
- Applications in security, communication, computing, sensing-measurements and quantum key distribution
Keywords: Quantum Optics, Integrated Quantum Photonics, Quantum Communication, Quantum Information, Quantum Simulation
