Quantum communication

Quantum communication is the use of quantum states of light or matter to transmit information in ways that surpass classical communication. Beyond cryptography, it enables tasks such as quantum teleportation, where the state of a particle is transferred without moving the particle itself, and entanglement distribution, which serves as a resource for quantum networks. It also supports future quantum internet infrastructures, enabling secure cloud-based quantum computing, distributed sensing, and clock synchronization with unprecedented precision. We have contributed broadly to quantum communication beyond cryptography, focusing on experimental demonstrations that push the limits of quantum networks. Our group realized quantum teleportation and entanglement distribution using multi-photon states generated via SPDC, enabling robust transfer of quantum information. We pioneered multiparty communication protocols, such as quantum secret sharing, Byzantine agreement, and clock synchronization, implemented over optical fibers. Additionally, we have performed several experiments on Quantum Random Access Codes and their applications.
