This is big!

Room Temperature Entanglement in a Semiconductor Substrate
It took less than a decade to go from a single cat-whisker transistor to commercial PNP transistors. Then another decade to get to commercial integrated circuits. If this is real, and if it translates to gate-type devices, the impact will be phenomenal.
Quantum entanglement achieved at room temperature in semiconductor wafers

""We know that the spin states of atomic nuclei associated with semiconductor defects have excellent quantum properties at room temperature," said Awschalom, Liew Family Professor in Molecular Engineering and a senior scientist at Argonne National Laboratory. "They are coherent, long-lived and controllable with photonics and electronics. Given these quantum 'pieces,' creating entangled quantum states seemed like an attainable goal."

In addition to being of fundamental physical interest, "the ability to produce robust entangled states in an electronic-grade semiconductor at ambient conditions has important implications on future quantum devices," Awschalom said.

In the short-term, the techniques used here in combination with sophisticated devices enabled by advanced SiC device-fabrication protocols could enable quantum sensors that use entanglement as a resource for beating the sensitivity limit of traditional (non-quantum) sensors. Given that the entanglement works at ambient conditions and the fact that SiC is bio-friendly, one particularly exciting application is biological sensing inside a living organism.

"We are excited about entanglement-enhanced magnetic resonance imaging probes, which could have important biomedical applications," said Abram Falk of IBM's Thomas J. Watson Research Center and a co-author of the research findings.

In the long term, it might even be possible to go from entangled states on the same SiC chip to entangled states across distant SiC chips. Such efforts could be facilitated by physical phenomena that allow macroscopic quantum states, as opposed to single quantum states (in single atoms), to interact very strongly with one another, which is important for producing entanglement with a high success rate. Such long-distance entangled states have been proposed for synchronizing global positioning satellites and for communicating information in a manner that is fundamentally secured from eavesdroppers by the laws of physics."

Stan,

Agreed.

This would mean that, it would actually be possible to produce static Mott Orbitals and "Trap" the electron, if theoretically analyzed as a wave function. Room temperature superconductivity would be ensured from semiconductor substrates, and not just talking about, "going from one medium to the other, when separated by a junction or a pseudo-gap". Also, no more Copper Pair BS.

Please do note that, it is also common to find quantum entanglement and quantum tunneling, when current passes from one junction to another, if they are doped differently. The problem is the "trail". Such phenomena happens in a lesser way than the scattering of the charge carriers, like with the depletion layer. It is scattering itself that may damage a semiconductor junction. This is the part which is not surprising, but the rest, actually IS, which may be the manifestation of Quantum Entanglement at a macro scale with THE WHOLE SUBSTRATE, which could be written as a Hamilton Equation.

Quantum Entanglement in a semiconductor means that, it would be possible to "ensnare" electrons in a particular orientation, and stabilized with particular, static orbitals, so that current may still be conduced without scattering of rest of the charge carriers, just as the Ohm's Law dictates. Non-ohmic electrical circuits are indeed a possiblity, leaving the open question of room temperature superconductivity.

Kind Regards.

Yonose,
I like that term, "non-ohmic circuits". Yep. There is lots of potential here. And not just for semiconductors; they have expanded the entanglement to hundreds of meters, as I understand it.

Here's another possible term: "non-time-domain circuits".

Also your comment about elimination of Cu return paths is a big deal, because it eliminates common mode noise.

Yes this could be a really big deal.

Stan,

It makes me think about Tesla's theories, as actual, experimentally proved, concepts from classical electrodynamics. Not everything in this world is going with a traverse wave and displacement currents.

If anything, Quantum Entanglement is part of the problem. Mainstream view of Quantum Electrodynamics should be revised. Nevertheless, we should not forget that, the understanding of the electron spin is connected with the generation of magnetic sources and quantum coherence.

Kind Regards.
