The step at 11:58 where (-1)^(a.y) is factored out seems confusing as ``(a XOR s). y" is not equal to ``(a.y XOR s.y)" also ``s.y = s1*y1 + s2*y2 + s3*y3 sn*yn", therefore its not guarenteed to be either 0 or 1 it can be 2 or 3 also, e.g., if s = (011) and y = (111) then, s.y = 2.

very clear about the steps of Simon's algorithm, thanks!

why do we can't just put 0 in black box ? 0 + s = s

What if "Wave Function Collapse" involves an annihilation + creation interaction with the Quantum Vacuum? The portion of the original "foreground" wave-function which collapses away is annihilated with "background" virtual (partial, off-mass-shell) anti-particles. The new portion of the "foreground" wave-function which regenerates into existence similarly arises from "background" virtual (partial, off-mass-shell) particles.

If so, and if you could affect the background population of virtual particles & anti-particles -- as with, say, some Casimir plates or something along those lines -- then you could affect wave-function collapse and (perhaps) skew probabilities in your favor.

Quantum Casinos can stack quantum decks in their favor?
