Minimal Experimental Test of Photon-Magnon Quantum Addressing: A Single-Channel Proof-of-Concept Proposal

  We propose a minimal experimental test to validate photon-magnon quantum state       

  transfer for memory applications. Using established YIG-cavity technology, we        

  demonstrate single-channel quantum addressing with one bit of information. Success   

  criteria: coherence > 1 microsecond, fidelity > 50%. Estimated cost: $50-100k with   

  existing infrastructure.                                                             

  This proposal is a companion to: "Towards Magnetic Field Quantum Memory" (Glamngiw, 

  2026), DOI: 10.5281/zenodo.18451271
