Entanglement Distribution in a Quantum Network: A Multicommodity Flow-Based Approach [PDF]
IEEE Transactions on Quantum Engineering, 2020 We consider the problem of optimizing the achievable EPR-pair distribution rate between multiple source-destination pairs in a quantum Internet, where the repeaters may perform a probabilistic Bell-state measurement and we may impose a minimum end-to-end

Information Scrambling in Quantum Neural Networks [PDF]
, 2020 The quantum neural network is one of the promising applications for near-term noisy intermediate-scale quantum computers. A quantum neural network distills the information from the input wave function into the output qubits.

Semidefinite Tests for Quantum Network Topologies. [PDF]
Physical Review Letters, 2020 Quantum networks play a major role in long-distance communication, quantum cryptography, clock synchronization, and distributed quantum computing. Generally, these protocols involve many independent sources sharing entanglement among distant parties that,

Simple method for asymmetric twin-field quantum key distribution
New Journal of Physics, 2020 Twin-field quantum key distribution (TF-QKD) can beat the linear bound of repeaterless QKD systems. After the proposal of the original protocol, multiple papers have extended the protocol to prove its security.

Entanglement generation in a quantum network at distance-independent rate [PDF]
npj Quantum Information, 2020 We develop a protocol for entanglement generation in the quantum internet that allows a repeater node to use n-qubit Greenberger-Horne-Zeilinger (GHZ) projective measurements that can fuse n successfully entangled links, i.e., two-qubit entangled Bell ...
