RULES:

---

"Normal" Schrödinger rules apply.
(i.e. place the digits 0 through 9 once each in every row, column and box;
two of the digits will have to share a Schrödinger Cell;
each row, column and box contains exactly one Schrödinger Cell).

• Kropki: White dots separate two cells containing digits of consecutive value; Black dots separate two cells where one digit is double the value of the other [ratio of 1:2] (not all dots are given).
• Renban (pink): Values along a Renban line form a set of consecutive, non-repeating values in any order.
• Nabner (gold): Values along a Nabner line form a set of non-consecutive, non-repeating values in any order (e.g. if a cell of value 3 appears on a Nabner line, then values of 2 and 4 cannot appear).

---

MODIFIERS:

---

• Schrödinger Certainty (Additive): Logical constraints are only concerned with the sum total of a cell.
• Schrödinger Certainty (Unique): Each Schrödinger cell must be a unique pairing of digits.

INTRODUCTION:

---

"Decoherence is the process by which a quantum state breaks down, often due to unwanted and uncontrolled interactions. Decoherence causes the state to collapse as if it was being measured."

Many thanks to gdc for providing the puzzle with a facelift!

Here are some puzzles from other setters using a similar constraint:
"The Graveyard of Schrödinger" by fjam
"Quantum Whispers" by tesseralis

Have fun!
