Not really fair to compare them by qubit number. Microsoft took a higher risk approach to quantum computing. Their qubits are based on majorana qubits. IBM has been doing the older more established method of superconducting circuits (Josephson junctions.) Which type of qubit is better in the long run is still up for debate. TL;DR Microsoft thinks they have a new type of qubit working.

The math and the physics is beyond me (you can't just use the old classical error detection/correction techniques we currently lose.) But from what I've read, there are ways to remove the errors - quantum error correction is an active field of research. The higher the accuracy you get the smaller the number of qubits you need to add to your system to handle the errors.

Look at the mess Linus Pauling made of his legacy with his medical quackery he started trying to sell in his later days. Simply because you are smart and well respected in one field, doesn't mean you've got a fucking clue in another. Some people don't get that.

What do you have in mind, would you please elaborate?

I'm guessing he's talking about Pauling's belief in taking megadoses of vitamin C. Seems like all the experiments have shown that it doesn't really help. Looks like the body has a certain amount of vitamin C that it wants and it will just expel anything over that

Comment Re:Mean error time ... (Score 2) 21

Besides Qbits I'd like people to provide the mean error time (if this is the correct term) for any quantum computer story in the media, i.e. for how long they can keep it in the coherent state - it would be quite useful. I also remember there were some issues with decoherence and extracting useful data out of the system - but maybe someone verse in the topic would provide more details.

Right now nobody has one that is useful. The errors are too great

Time able to stay in a coherent state is a little misleading. Using ions means your quantum state is stable. The rub of it is that it is so stable that it takes a much longer time to do an operation. This causes it to have too much error by the time you operation is done

superconducting semiconductor qbits meanwhile are fast to perform operations. But at the same time they decohere quickly since it is so easy to perform operation on them

My experience is that 60% of the people using them aren't really disabled. Just people who are in horrible physical condition from not moving around and eating too much. If you really wanted to help them, you would force them to the end of the parking lot so they could get more exercise.
