"overcomes critical quantum bottleneck: emitter coherence time... Energy Quantum Confinement Effect: total decay rate Γ dipping below γ₀, by dynamically trapping energy quanta within waveguide, creating quasi-bound states partially offsetting local dissipation... converts energy loss into temporary storage, bypassing the rigid limits of traditional Markovian systems... scaling to multi-emitter systems enhances effect...a leap towards fault-tolerant technologies and the scalable quantum networks of tomorrow"
