Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state. In a quantum network, this protocol can be …

We consider multipath generation of Bell states in quantum networks, where a preprepared multipartite entangled two-dimensional cluster state serves as a resource to perform different …
Quantum Cryptography (QC) revolutionizes network communication–harnessing principles of quantum mechanics to enable the exchange of encrypted messages–for enabling secure …

We consider entanglement-based quantum networks, where multipartite entangled resource states are distributed and stored among the nodes and locally manipulated upon request to …
Future quantum technologies such as quantum communication, quantum sensing, and distributed quantum computation, will rely on networks of shared entanglement between …
Motivated by quantum network applications over classical channels, we initiate the study of $ n $-party resource states from which LOCC protocols can create EPR-pairs between any …
Despite the exponential overhead to describe general multiqubit quantum states and processes, efficient methods for certain state families and operations have been developed …
Entanglement-based quantum networks exhibit a unique flexibility in the choice of entangled resource states that are then locally manipulated by the nodes to fulfill any request in the …
We study the notion of $ k $-stabilizer universal quantum state, that is, an $ n $-qubit quantum state, such that it is possible to induce any stabilizer state on any $ k $ qubits, by …
