Multi-Pair Fidelity-Aware Rate Allocation in a Quantum Network: Approximation Schemes

This paper forms three rate-allocation problems: rate sum, rate sum subject to minimum-rate constraints, and max-min fairness, and presents fully polynomial-time approximation schemes (FPTAS) for solving these optimization problems.

Efficient routing and spectrum allocation in arbitrary flex-grid entanglement networks

As practical quantum networks approach large-scale deployment, the need for efficient user-to-user frequency allocation is increasing, yet current approaches only provide partial solutions to the routing and spectrum allocation problem for an arbitrary quantum network. We address this challenge for repeater-less flex-g...
