What has feasibility got to do with cost? NMR's with superconducting magnets are perfectly feasible. And not cheap. My last company, Firmenich, in Geneva has a nice one running 24/7 analyzing the results of organic synthesis.
And anyway, price for a basic benchtop NMR in 2020 ... $50k

Any new electronic technology pretty much halves in cost every year once it's commercially widespread.

In your original post you wrote "quantum computing still theory, can't be done as the quantum computer doesn't exist."

Now you admit you were wrong and prove it with your own quote " A large number of candidates demonstrates that quantum computing, despite rapid progress, is still in its infancy."

Infancy is a long way from "doesn't exist"
...I mention ''maybe another 20 years''...for me practically doesn't exist...at the state they exist now, they solve problems a lot slower than usual super machine...
...researchers took wrong path, they should use quantum optic...as it easier to harness...plus have more possibilities: An individual photon can be described as having right or left circular polarization, or a superposition of the two. Equivalently, a photon can be described as having horizontal or vertical linear polarization, or a superposition of the two...

Sort of but conservation of energy gets a bit messy at the quantum level.
How can you say a certain quantity does not change with time if when you try to reconcile quantum mechanics and general relativity there is no space time or time runs in either direction.
My poor explanation probably has holes as it is all a step too far for me.
...Energy at each fixed time can in principle be exactly measured without any trade-off in precision forced by the time-energy uncertainty relations. Thus the conservation of energy in time is a well defined concept even in quantum mechanics(Wikipedia)...

Nothing I could disagree more with.

In the field of astrophysics: we are discovering exoplanets on a regular basis (over 1000 by now), observation of universe inflation

In materials: invention of topological insulators. This is the fundamental science that will open millions of doors for electronics in the years to come. Invention of graphene/carbon nanotubes.

In experimental physics: as I mentioned earlier, the discovery of the Higgs boson, the measurement of the neutrino mass, the entire field of quantum computing (a future breakthrough will still come from Einstein, when we manage to apply Bose-Einstein condensate to facilitate superconduction), reproduction of quantum teleportation.

I don't mention the detection of gravitational waves because they were predicted by Einstein.

As an engineer you will GREATLY appreciate learning more about TI. This is a great introduction (you do need to have a working understanding of quantum physics).

The uncertainty principle is already using in tunnelling microscopy.

General relativity didn't really gain any practical use until it was needed to make GPS feasible, so that's a gap of about 60 years.

Plenty of time to find practical uses for the others if not already, although it is likely to be a while before black hole evaporation becomes useful.

Exactly.
And I think some people think of quantum teleportation as being the teleportation of something physical, but what it is is the "teleportation" of information.

I know that in 2017, Chinese scientists had set a record for teleporting the quantum state of a photon from Tibet to a satellite in space.

Re: Ask a Scientist

Kite, I see your bullet points, your half sentences, and your quotes, and to me they are not a lot different from:
  • How should you navigate this consciousness-expanding grid? The dreamscape is calling to you via superpositions of possibilities.
  • That rabbit above a moon milked that earthy shrubbery above this robust finicky perspicacious ball.

1) ...the so called teleportation between two chips used the same silicon...

What's your argument? They used silicon, in as much as "they sent photons from earth to a satellite with a laser, and the laser has chips, partly made of silicon". What do you mean "they used silicon" ?

2) ...for transmission they used an resonator, which automatically implying waves...

Again, what are you talking about? They used a laser, and light behaves also like a wave. So?

3) ...where is a wave is a mass and consistency...''nothing'' can't vibrate...

Photons are the quantum of EMF which is a wave, so I'd say "no", wave does not equal mass.

4) ...https://www.nature.com/articles/s41567-019-0727-x...

To that Nature abstract, I reply: https://bit.ly/3oBv2yO

5) ...this is pure transmission, not teleportation...

This is a common misunderstanding. Quantum teleportation does NOT mean teleporting matter. It refers to teleporting information within a single particle. The entangled photons in the experiment "carry" information inherently encoded in their quantum state, which can be either vertical-vertical, vertical-horizontal, horizontal-vertical and horizontal-horizontal. If you wanted to encode that information in ASCII text, you could store it as "vv", which is 2 characters. A shorter form would be to set up an equivalence of vertical=0 and horizontal=1, so you could beam two binary values. Any way of ultra-simplifying the "information" takes more than a single photon. See how this is "teleporting" information?

No, that is NOT what they did at all (BTW, silicon is not carved as marble is, it's melted, moulded, and sliced).

It was a question? I thought it was a statement. Anyhow...you're missing the point of teleportation because you didn't think of the time axis. You're thinking that the laser fires a photon, and they read its state when it arrives. That's not what the experiment did. They created 3 entangled photons, and fired one of them to space. At the same time when the photon arrives at the detector, they measure the photon still at the base, and its state is INSTANTLY teleported to its remote entangled sibling in space. That is the information that is teleported. Keep in mind that the quantum state is only a probability wave as long as it's not measured, and the wave function collapses upon detection, so simultaneous entangled state detection, happening at the exact same time, without any time delay, is proof of information teleportation.

Since the practical utility of new physics seems to be a bee in your bonnet, here are some useful bits of physics discovered since Einstein:
- Semiconductor physics
- Theory of turbulence
- Theory of polymer physics (de Gennes Nobel prize)
- Theory of liquid crystals (ditto). Some idiot journalist said that he had invented LCD watches. All of de Gennes work was useful. See also his work on wetting of surfaces and drop formation.
- Theory of fractals and experiments too. Mandelbrot first worked on noise on telephone lines for IBM.
- Chaos theory and experiments.

There are plenty more.

Re: Ask a Scientist

Summary
  • Lots of people have advanced every branch of physics over the past few decades
  • Even more people, including quite a few on EF, make use of these new discoveries and developments
  • Almost everybody is aware of the rapid growth of knowledge in physics and its application to solution of problems
  • Some bloke on the internet called Flying Kite isn't.

Suggestion
  • Let's get on with our lives and let the non-believer(s) get on with his/hers.

...is no empty space in whole universe, all spaces exists are filled with something, in 80% of cases with hydrogen, light from the stars to reach us use hydrogen as transportation...
