High-Q cavities are suitable physical systems for realizing several quantum information processing tasks. A series of such cavities are coupled to form a cavity array, enabling the transfer of photons from one end to the other. This photon transfer can be controlled by embedding specific materials, such as atoms or Kerr nonlinear media, into the cavities. These setups are not just limited to the photon transfer; they are also ideal for exploring various aspects of quantum physics, quantum information processing protocols, and quantum thermodynamics through experimental studies.
Recent advancements in technology have made it possible to create high-Q cavities using photonic crystals, superconductors, and whispering gallery modes of materials like silica and quartz. These advances have allowed for more precise and sophisticated cavity experiments, paving the way to answer numerous unresolved questions in the field of quantum physics.
A quantum network, comprising several high-Q cavities, facilitates the sending and receiving of information, the creation of entanglement, and the execution of quantum gate operations. These features are essential for developing a robust cavity-based quantum network, which could serve as the architecture for a future quantum internet. However, there are still technological challenges to be addressed, particularly in achieving distributed quantum communication and quantum computation using quantum cavities.
The main objective of this Research Topic is to showcase the suitability of quantum cavities for various quantum mechanical applications. These applications include quantum information processing, the generation of non-classical states of light for quantum metrology, and the exploration of quantum thermodynamics.
This special issue aims to highlight studies focused on both the fundamentals and the cutting-edge developments achievable with quantum cavities. We encourage researchers to submit research articles or review papers in the following areas and related domains:
• Cavity quantum electrodynamics
• Quantum information processing and communication
• Quantum computation
• Quantum metrology
• Quantum optomechanics

• Quantum thermodynamics
We emphasize that this list is not exhaustive, and contributions in related areas are also welcome. Through this collection, we aim to further our understanding and capabilities in the fascinating field of quantum cavities.
