Resum
We review the optimal protocols for aligning spatial frames using quantum systems. The communication problem addressed here concerns a type of information that cannot be digitalized. Asher Peres referred to it as "unspeakable information." We comment on his contribution to this subject and give a brief account of his scientific interaction with the authors. © World Scientific Publishing Company.
