Would it be possible to determine/ capture the total wave function of an ensemble using quantum tomography & weak measurement ?

As seen in the following article.. Its been done on a photon.. My question is, could this same technique be done on an ensemble of particles ?

Whether it be a mouse brain, 1TB hard drive or a full fledged computer system,

then host" the 3d information / MRI info of said object,

(using the wave function as a monad to generate the object)

As seen in some quantum computing Haskell sources..

Thereby setting up a symmetric entanglement between the two systems without causing collapse of the system being measured due to the weak measurement process ?

In essence, constructing a Hamiltonian of the cloned system so that it may be modelled and hosted in virtual space on a quantum computer ?

Is there any truth to this idea ?

Could you in ANY way, sustain "macroscopic" entanglement, MICROSCOPICALLY ?

As mentioned in such university papers as so...

"Quantum entanglement of baby universes"

"ABSTRACT We study quantum entanglements of baby universes which appear in non-perturbative corrections to the OSV formula for the entropy of extremal black holes in type IIA string theory compactified on the local Calabi–Yau manifold defined as a rank 2 vector bundle over an arbitrary genus G Riemann surface. This generalizes the result for G=1 in hep-th/0504221. Non-perturbative terms can be organized into a sum over contributions from baby universes, and the total wave-function is their coherent superposition in the third quantized Hilbert space. We find that half of the universes preserve one set of supercharges while the other half preserve a different set, making the total universe stable but non-BPS.

The parent universe generates baby universes by brane/anti-brane pair creation, and baby universes are correlated by conservation of non-normalizable D-brane charges under the process.

There are no other source of entanglement of baby universes, and all possible states are superposed with the equal weight."

Would it then be entangled with its real world counter part residing in the "parent" universe ?

Could this same method not be applied to nearly anything, so long as it is placed into the phase space of the "child" baby universe ?

Now many might thinking.. Even if you could do this.. Making observations of that system would collapse its state, making the simulated system decohere...

Not so according to this source..

Are there any physicists out there willing to theorize with me ?
