Coherence time is the operative limit to SOTA QC Quantum Computing.
Holographic data storage already solves for binary digital data storage.
Aren't diffraction patterns due to lattice irregularities effective wave functions?
Presumably holography would have already solved for quantum data storage if diffraction is a sufficient analog if a wave function?
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
