About this Research Topic
Lasers have placed optical science in a unique position to study fundamental physics and also revolutionize future technologies. As an increasing number of systems are moving towards automation, the prominence of laser-based sensors is experiencing a corresponding increase. The coherent nature of a laser makes it an excellent probe, while the quantum nature of photons imparts quantum mechanical advantages. Quantum optical metrology combines the advantages exhibited by lasers with quantum metrology principles. Such a combination allows us to develop the next generation of quantum technologies such as quantum computers, quantum teleportation, and quantum information, amongst others.
Future technologies will be based on quantum mechanics. The successful design of every quantum device relies critically on the efficient generation, storage, and transfer of the appropriate quantum correlations. However, these correlations are highly susceptible to decoherence. For example, squeezed states form one variety of quantum correlation which facilitate an improvement in precision measurement. To date, the largest squeezing achieved is 15 dB, which is adequate, but much greater values are required for next-generation applications. Similarly, entangled states form another variety of correlation which is an essential component in quantum teleportation and quantum computing, amongst other applications. At present, entanglement is highly susceptible to environmental decoherence and, as such, the development of efficient synthesis and quantum correlation preservation methods is imperative. A further issue is the loss experienced by quantum correlations during the transfer from one system to another. This Research Topic aims to address and evaluate challenges related to the efficient synthesis of quantum correlations and their subsequent application in quantum optical technologies.
Within this Research Topic we look to gather original research articles and in depth review articles concerning the theoretical and experimental investigation of issues related to optical quantum storage, optical quantum state generation, and the transfer of quantum correlations using optics. In addition, novel approaches which look to tackle quantum noise and quantum decoherence in optical sensing are also welcome.
