About this Research Topic
As such, a Research Topic reporting on the continuous-variable quantum optical states and their varied applications is well-timed. Cat Code, PT-symmetry, and exceptional points have each been experimentally demonstrated. The corresponding open quantum system is currently being investigated under realistic conditions. Quantum optics is of particular relevance to a number of applications, including Quantum Key Distribution, quantum communications, information processing, quantum metrology, and quantum sensing.
Topics of interest include, but are not limited to, the following fields:
- Generation of nonclassical light states.
- Quantification of non-classicality.
- Metrological application of continuous-variable states.
- Weak measurement in optics.
- Sub-Planck structures, interference in phase-space, and their applications in precision metrology.
- Quantum light for information processing.
- PT symmetry and non-Hermitian system in optics.
- Applications to quantum sensing and imaging.
Keywords: Optical Quantum State, Quantum Key Distribution, Quantum Communication, Gravitational Wave Detection, Sub-Planck structure, Quantum Metrology
