A hybrid GHZ-BSM routing strategy outperforms pure BSM routing in square grid quantum networks but requires global-information adaptations to beat BSM in complex topologies such as Waxman, scale-free, and SURFnet.

Introduces entanglement and fidelity absorption capacities for separable noise in Bell mixtures, with closed-form results for product states and X-states plus extensions to channels and bounds.
Monolithic Si3N4 platform achieves EPR fidelity 0.9875(3), HOM visibility 0.990(6), and four-photon GHZ fidelity 0.943(8) at 27 Hz—more than 100x prior silicon-photonic rates—using CMOS-compatible 150 mm wafer fabrication.

An inverse design framework based on guided-mode expansion and automatic differentiation optimizes a non-periodic circular cavity to a quality factor of ~9000 with Gaussian-like far-field emission, an order of magnitude above periodic bullseye designs.
Q-GUARD achieves over 85% qualified success rate on 4-hop paths in 100-node simulations by allocating per-hop fidelity targets via Werner-state equal-split and selecting paths with a segment-local expected-goodput metric.

A state discrimination game on energy-restricted quantum states creates a hierarchy of optimal success probabilities that certifies multipartite entanglement structure.
Bayesian optimization reliably identifies optimal protocols that maximize secret-key rates for heterogeneous quantum repeater chains with arbitrary nodes.
A quantum anonymous secret sharing scheme is constructed using permutation-invariant codes, with leakage in ramp schemes quantified by quantum conditional min-entropy related to Knill-Laflamme conditions.
Depolarizing channels suppress the correlations needed to witness both state-dependent and state-independent contextuality in sequential KCBS and Peres-Mermin implementations, leading to classicalization.
Arqon delivers reliable quantum network service via admission control and scheduling that satisfies defined reliability requirements for accepted demands in static topologies, with O(k^3) and O(N^3) complexity.
Higher-dimensional two-way QKD protocols using mutually unbiased bases and Heisenberg-Weyl operators yield secret keys for stronger individual attacks and improved robustness to collective eavesdropping via entropic uncertainty relations.
The paper introduces a modular, hardware-agnostic architecture using entanglement packets for scheduling network operations in quantum networks to enable end-to-end entanglement generation integrated with local program execution, demonstrated via simulation on a 6-node star topology.
Negative quantum states from discrete Wigner functions show resilience advantages over Bell states under non-Markovian dynamics, are protected via weak measurements, and are realized on IBM superconducting hardware.
