Quantum-safe sudoku
(Published on 26. September 2022, 20:11 by chameleon)
Normal Kropki dots rules apply (no negative constraint).
Cages are Schrödinger cells - they contain one of 2 values. After filling all regular cells with digits, all Schrödinger cells must remain unresolved (in other words, both values of every Schrödinger cell must allow for a valid sudoku solution).
The quantum balance of the universe is safe with this sudoku. Cats are safe too.
Solve online: CTC app
Solution code: digits of row 8, no whitespaces

Wow, just wow! I loved figuring out the break-in, and how it unfolded (untangled?) from there. A superb puzzle!

Unique and brilliant! This felt like a "level up" moment for me as a solver, thank you very much!

No idea how i solved it. It was like matrix. I kept restarting the puzzle thinking i am doing something wrong but approach was right all along i guess.

Gorgeous puzzle, elegant idea and construction with so little clues (and especially not a single numerical clue)! I enjoyed solving it a lot!

Wow! This was mind boggling :-)
Beautiful, novel and mesmerizing. I'm still amazed it actually has a solution - Schrödinger's (safe) cat would be proud :-)
Note, you might want to add "row" before the 8 in the solution code... :-)

Thank you! :)
Both for the kind words and for correcting the solution code description
