About this Research Topic
Quantum Information Processing (QIP) through continuous variable (CV) non-classical optical quantum states represents a cutting-edge field in quantum physics. These states, notably squeezed and cat states, have been harnessed under controlled environments, signifying a step forward in the computational and information processing arenas. Moreover, their use in quantum sensing and metrology highlights their practical implications, particularly in areas such as gravitational wave detection through precision metrology. Despite these advances, the broader application of cat and kitten states in various domains underscores an ongoing expansion in the field's scope and relevance.
This Research Topic aims to systematically explore, analyze, and expand upon the current computational strategies and application frameworks involving CV quantum optical states. The investigation into the intersection of quantum optics and non-Hermitian systems, alongside the development of quantum memory and repeaters within quantum networks, promises to push the boundaries of current technological capabilities. Furthermore, the exploration of PT-symmetry and exceptional points under realistic conditions offers a compelling vista into the quantum optical paradigm.
To gather further insights in the potential and challenges of continuous-variable quantum states, we welcome articles addressing, but not limited to, the following themes:
• Generation of nonclassical and superradiant light states;
• Non-classicality metrics, and quantum entanglement within and between particles;
• Metrological uses of CV states, including frequency comb generation;
• Weak measurement techniques in optics and their applications;
• Exploration of sub-Planck structures and fractional revival in precision metrology and sensing;
• Innovations in quantum light and structured light for enhanced information processing and imaging;
• Challenges and advances in PT symmetry and non-Hermitian optical systems;
• Expanded applications in quantum sensing techniques;
• Optical quantum circuits and their implications for quantum games;
• Utilization of optical lattices in ultra-cold systems.
