    If Qubits can be in several states at once, how do you even go about setting them up in any meaningful way to produce a useful output?

                                Basically they are hoping to make a multicore out of single core and reduce the feature size. Going below a certain feature size make transistors hard to make. Therefore the gates are formed in a different manner but still obey much of the same logic. The speed on the processor is still governed by a frequency of control logic, which will serialize the parallelization. Algorithms will need to attempt to make the right guesses in the right sequence to make it work. Doesn't this negate the gains of reducing the feature size? My point is the feature size generally allowed more transistors, here the speed is governed by the control logic and algorithm. This could make the hardware logic difficult to manage. This indirect management really messes stuff up. This was the cool thing about transistors is they just need voltage which they could produce. Basically they are trying to leverage a Turing machine and hope to make it useful.

                                By the way those logic gates would short like crazy. They were not CMOS or even PMOS/NMOS.

                                    Ich finde diese Videos an sich sehr interessant, finde aber Aussagen wie "Die Grenzen der Technologie" oder so einfach unpassend da engstirnig. Immer wieder haben die klügsten Köpfe einer Zeit behauptet, mehr ginge nicht. Man meinte mit felsenfester Sicherheit "So! Dieses mal ist auf jeden Fall das Limit erreicht.", und immer wieder kam doch noch was neues.

On the upside you can use the simulation to find other laws we didn’t even know about, mainly by trial and error of making a universe that has the exact same laws as ours. When we finally make it so they’re exactly alike, we can test our theories in it and see what is correct and what isn’t. Man, get the quantum computer finished already!!! DX
