Quantum communication and quantum key distribution

I have studied the role of squeezing and entanglement in the discrimination of quantum states in the presence of dissipation. My recent results concern the discrimination between continuous-variable optical states in the presence of noise during the propagation and detection stage (J. Opt. Soc. Am. in 2022, J. Opt. Soc. Am. B in 2023).

I have proposed hybrid discrimination protocol based on coherent states and PNRs (Phys. Rev. A in 2018) and developed a novel receiver (hybrid near-optimum receiver, HYNORE) to exploits both wave- and particle-like nature of the optical states to enhance the performance of quantum communication (J. Opt. Soc. Am. B in 2023).

I also investigate new schemes to implement quantum key distribution (Phys. Rev. A 2018, Phys. Rev. A in 2023).
