Consider a photon quantum linked to 100 other photons. If the main photon travels a Planck length, yet the 100 other photons it is linked to are in a modulatable environment. These could then be capable of causing fractional spin at the main photon. You could change spin at less than a planck unit.

Also,
unrelated and epistomologically dense of me, but i am wondering that 1) if there has to be something that is there and 2) blue shift occurs between two things could 3) the planck length be blueshifted to make an eentsier planck length?

// the planck length be blueshifted to make an eentsier planck length? //

No, because blue shift is a function of the observer's frame of reference. The Planck length is only valid if the observer and the thing observed have a common (isosynchronous) frame of reference.

You can't apply Bell's theorem of quantum entanglement because (again) that relies on a common frame of reference. As soon as you move one of the entangled objects at relativistic velocities, you decouple it.

[suggested-for-deletion] blatant and wilful misunderstanding of Quantum physics.

No, because it's at both points simultaneously; it just depends where the wave function is collapsed, which then fixes its position (destroying the photon in the process).

[8th] What do you think of the 100 quantum linked photons nudging the spin of the photon? As a technology I imagine this might be "sub planck length" tweezers, just a little like AFM.

Also, it isn't actually "wilful" just regular old ignorant

I think you will find that if a photon's wavelength was
smaller than a Planck length, such that it could possibly
traverse that length, the energy content of the photon
would be so high that it would collapse into a black hole.
There is a reason why the Planck length is the MINIMUM
THEORETICALLY POSSIBLE length in physics!

//the Planck length is the MINIMUM THEORETICALLY POSSIBLE length in physics!

"Great fleas have little fleas upon their backs to bite 'em, And little fleas have lesser fleas, and so ad infinitum." You never know, it might be little and littler Plancks all the way down..

Since mathematics doesn't know when to stop, it knows smaller than the reality of the Planck length, a computer could model a grain smaller than said length. A fraction of a photon.

The problem, though, is what attributes are supposed to be given to this "eentsier'" thing. Get it right and the object's action would scale/recurse up to the physics we all have a love/hate relationship with.

Something squishy but very slippery. A tiny oiled breast implant like object.
