Description
Quantum communication exploits the properties of quantum states to enable secure information transfer. Over the past several decades, quantum key distribution has become the dominant approach to quantum-secure communication, where a shared secret key is first established before encrypted communication takes place. An alternative approach is direct quantum communication, in which the message itself is transmitted using quantum resources. Continuous-variable optical systems provide an attractive platform for implementing quantum communication protocols owing to their compatibility with standard optical technologies and mature quantum optics techniques.
In this presentation, we discuss an experimental investigation of a continuous-variable direct quantum communication scheme based on squeezed states. The work explores the implementation of the protocol in a laboratory setting and examines its behaviour under passive optical channel conditions. The presentation will outline the experimental approach, discuss representative results, and consider the opportunities and challenges for continuous-variable direct quantum communication.
