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 Al+ single-ion clock is evaluated at 1.6×10^{-18} systematic uncertainty with absolute frequency 1121015393207859.19(24) Hz and ratio to Sr clock of 2.611701431781462668(36).
Emulation of ring, star, and line topologies for quantum data centers on a quantum computer shows the star layout yields the best cost-fidelity trade-off under transduction and fiber noise.
Most institutions should start with the smallest quantum capability layer that delivers repeatable near-term value and builds expertise rather than acquiring large on-premises systems.
