Research proves the Petz transpose map is the unique solution for quantum retrodiction—inferring past quantum states from present measurements—when consistency principles of channel composition and reversibility are satisfied.

Quantum Retrodiction Follows Unique Map With Three Consistency Rules
Until now, establishing *why* the Petz transpose map appears across diverse areas of quantum theory remained an open question. This work proves that, given four specific conditions, including respect for sequential composition and unitary inversion, retrodiction assignments are uniquely defined by this very map. The finding clarifies fundamental principles governing reverse processes directly through channel reversal consistency requirements.

Pebble Smartwatch: A Jyotish Tarot Retrodiction
For this historical test, I explored the original Pebble smartwatch Kickstarter campaign, launched in April 2012 with a $100,000 fundraising goal. As I shuffled, I decided to pull 8 cards for the spread instead of the usual 7. The 8th card in the Navatara sequence is “friendship,” “ally,” and companion”. It is an auspicious position. Then I changed my mind, did the 7-card spread, and interpreted it before learning the outcome.
