We study the fundamental and practical aspects of continuous-variable (CV) quantum information processing, using Gaussian and non-Gaussian resources.
Optical quantum computing
Entanglement distribution and manipulation
Quantum teleportation and its applications
No-cloning bound and secure communication
We explore nonclassicality and non-Gaussianity as fundamental quantum resources to enhance quantum advantage. Our research investigates their theoretical characterization, quantitative measures, and operational significance in applications of quantum information processing.
Detection/quantification of nonclassicality and non-Gaussianity
Non-Gaussianity from the perspective of quantum resource theory
Non-Gaussian quantum state generation
We stydy quantum error correction codes for protecting quantum information against decoherence. We aim to realize fault-tolerant quantum computation compatible with realistic physical platforms. We especially focus on bosonic error correction codes.
