Protecting Entanglement of Photons with Symmetry

Protecting Entanglement of Photons with Symmetry.   Research conducted at the Karlsruhe Institute of Technology further proves quantum entanglement (quantum states) may be preserved when passing through nanoscale holes.  The quantum computing nexus is the preservation of quantum information when passing through these waveguides.  The waveguides are envisioned as quantum computing devices fundamental to a quantum computer.  Decoherence and disentanglement of the photons, being major challenges to bringing quantum computers to fruition, may be reduced or eliminated via their method.
