Quantum Sudoku

(Published on 10. October 2020, 00:12 by meowzzz)

Normal sudoku rules apply, except for the red cells!
Fill each row, column, and box with the numbers 1 through 9.

Killer cage rules apply.
Numbers must not repeat and must sum to a given total in the top left of the cage.

Sandwich sudoku rules apply.
The sum of the numbers between the largest (9) and smallest (1) number in the row or column must match the number indicted outside the grid.

The red cells are in superposition:
Normal sudoku rules DO NOT apply
Red cells are 3 digits simultaneously, and don't need to be filled in.
Each digit must be different when measured/observed from row, col, and box.
Sandwiches measure red cells along the column or row they are on.
All red cells share the same 3 digits.
All red cells are given.

The blue cells are entangled:
Normal sudoku rules apply.
Must use the same 3 digits used by the red cells.
Not all blue cells are given.

Example:
https://f-puzzles.com/?id=y3t8sknp
The red cells are determined to be the digits {2,3,9}.
When measured it is {box=9, row=3, col=2}
When the 35 sandwich on row 3 is measured it uses the the red number along the row which is a 3.
The blue cells match the digits {2,3,9}.
In box 1, r2c3 = 3 and r3c2 = 2
In row 3, r3c2 = 2 and r3c9 = 9
In col 3, r2c3 = 3 and r5c3 = 9

Absolutely fantastic puzzle! Not hard but very very creative and enjoyable logic.

I would just change the wording of solution code for:

"The measurements of Row 5 followed by Column 5"
