Austria is probably the English-version of the German name which translates to "Ost"- Eastern + "Reich"-empire.

It's a surface integral of a vector F over a surface S. I guess they are extending the joke from 1D to a 2D surface which is smoothly integrated (peeled).

A woodchuck would chuck as much wood as a woodchuck could chuck if a woodchuck could chuck wood. It's a classic tongue twister! Would you like to try another one?

I got this from Gemini.

Percutaneous: means "through the skin"

Transhepatic: means "across the liver"

Portal vein: a major vein that carries blood from the intestines to the liver

Transplantation: surgical procedure involving the removal of an organ or tissue from one person (donor) and placing it in another person (recipient)

Just use LLM these days!

I think they got confused between 'unreal' and 'ethereal'.

These qubits oscillate at microwave frequencies where the quantum information is stored. This means they need to be kept at a temperature where the microwave frequencies are completely devoid of any thermal noise. For microwave frequencies, this temperature is just a few millikelvins above absolute zero. Unfortunately, the temperature is required due to the fundamental nature of thermal noise due to temperature. Making the qubits out of room temperature superconductor would not solve the problem of the need to cool them down - unless they can be operated at higher frequency. There are quantum computers made using light/optical photons which do operate at room temperature because optical photons are at much higher frequency which has no thermal noise even at room temperature.

So, in conclusion, everytime you hear about superconducting qubit, they are always in a giant dilution refrigerator which gets bigger for more qubits as more connections from room temperature to qubits are needed.

For now they are only being used for research purposes. For example, simulating Quantum effects in many atom physics and implementing error correction for future quantum computers. Any real applications still need some time but the pace of development is really quite something.

We are still not sure. The paper was published under very suspicious circumstances. However, since the recipe is given in the paper, many groups around the world are running tests. We still need to wait a few more days for more conclusive results. With the results until now, it seems that the material is at least very strongly diamagnetic but I haven't seen any conclusive proof of zero resistivity confirmed by another lab.
