Encrypted Cloning, Absolute Maximal Entanglement and Quantum Secret Sharing
Zheng Liang Lim, Hoi-Kwong Lo
The no-cloning theorem prohibits the creation of identical copies of quantum information, imposing fundamental constraints on quantum technologies. A recently proposed protocol, en…
Cost-aware Photonic Graph State Generation: A Graphical Framework
Sobhan Ghanbari, Hoi-Kwong Lo
Photonic graph states are essential resources for quantum computation and communication. Deterministic emitter-based generation of graph states overcomes the scalability issues of…
Distributed Symmetric Key Establishment: a Scalable Quantum-Safe Key Distribution Protocol
Jie Lin, Hoi-Kwong Lo, Jacob Johannsson +2
Pre-shared keys (PSK) have been widely used in network security. Nonetheless, existing PSK solutions are not scalable. Moreover, whenever a new user joins a network, PSK requires a…
GraphiQ: Quantum circuit design for photonic graph states
Jie Lin, Benjamin MacLellan, Sobhan Ghanbari +6
GraphiQ is a versatile open-source framework for designing photonic graph state generation schemes, with a particular emphasis on photon-emitter hybrid circuits. Built in Python, G…
Optimization of deterministic photonic graph state generation via local operations
Sobhan Ghanbari, Jie Lin, Benjamin MacLellan +3
Realizing photonic graph states, crucial in various quantum protocols, is challenging due to the absence of deterministic entangling gates in linear optics. To address this, emitte…
