Is a diffraction pattern a wave function?
E.g. a scratched microscope slide is all wave functions.
Can (crystal,) lattices be constructed and/or modified to store diffraction patterns with sufficient coherence over time?
...
(Array of) photonic sensors and coherent light sources; like NIRS
Multi-beam waveguiding
Quantum dots in DNA with hard glass coating would thus have a hard glass substrate for qubit storage
