Thanks, Q-reeus. I didn't know about this paper. The authors write:
Such an observation could undermine the assumptions of superposition and entanglement, bringing into question the foundation and the ultimate performance of a universal digital quantum computer.
And the same authors proposed a different experiment probing entanglement-or-not, involving single-photon measurements:
https://arxiv.org/abs/1407.2605Less clear to me what could really be inferred from any results there.
As for my
proposed experiment, there isn't enough political will in the community to take a risk of actually performing it. The will of the community is in investing literally billions of dollars in the dream of quantum computers.
No question in my mind bandwagon effect is the reality for so much of establishment science. On a different tangent, the brilliant Laszlo Kish et. al. has shown that robust, practically attainable exponential speedup can very likely be had via clever use of the very thing QC crowd strive extremely hard to avoid - noise!:
